If their profile picture looks professionally done and can be found on a modeling website, chances are the person stole the picture. Sure, they may just be a lonely model, but how likely is that? You can use Google's image search or other reverse image search sites to see if this picture shows up on a stock image site. If someone is desperate to sound good, they may not remember that something like 6' and 95 lbs is not proportional, unless their diet is insane. It's up to you whether you're willing to get involved in an affair or not, but just remember this: if they've lied about their marital status, what else could they be lying about? A scammer's occupation is usually some type of "Engineer" for men and a "Model" for women. It's just another way to make themselves sound like a good pick. Engineers make heaps of money, and models normally look beautiful. Now doesn't that sound amazing? Use this to do a Google search to see if shows up on other websites. If the profile is for another photo or perhaps man or woman, this person may be using the words verbatim and is a fraudster. For example, ask things such as "What is your favorite character on the TV show?" that they listed. If they list they have a specific car or boat; check what kind of mileage they get or brand of boat. Ask about a particular restaurant in the city and Google the address. Ask how to get there from another easily accessed address close to this; for example, McDonalds is on First Street there, so is that next to the XXXX? Google Maps will usually show street names and even a street picture to help you gauge the accuracy of the response.

If you feel that you made a mistake in the relationship and have attempted to make amends, move on. Don't be hard on yourself for things that you cannot change. To help alleviate guilt, try reminding yourself what you did right, either in the relationship or outside of it. Envision a time when you were supportive, loving and loyal to those around you. Determine who is behind the guilt that you're feeling. Are your friends wishing you would get back together with your ex or is he manipulating you in some way? Determining which feelings are someone else's and which are your own is important for figuring out if the guilt is warranted or not. If you had a favorite restaurant that you frequented together, make it a point to still eat there. Make reservations to go with friends in order to create new memories. This will keep you from limiting yourself and letting your sadness dictate your actions. If you shared a mutual friend with your ex who you still care about, try not to let the nature of the friendship change now that you're no longer together. Remember that starting a new relationship doesn't mean it will end like your last one did. Concentrating on how you feel you were wronged will make you appear bitter and unpleasant to be around. If you hold onto these feelings, you could miss the opportunity to meet someone amazing in the future. Allow yourself to learn from past mistakes, but understand that no two men are the same. If you begin to notice an unhealthy pattern within your relationships, consider how you can avoid this. Whether it's being taken advantage of, or letting a negative side of your own personality take over, recognize that failure to change this habit will result in a similar outcome. If the type of man that you're drawn to keeps hurting you, address the reasons behind why you're drawn to this type of relationship. Talk with those closest to you who saw the nature of your relationship first-hand. Ask them for help in constructively evaluating what went wrong with your ex. Chances are that if your break up is fresh and you are still healing, even a friendship isn't possible between the two of you for now. It will be difficult to have an objective viewpoint on what went wrong if you're still in contact. Additionally, it may make it harder for you to accept the end of the relationship, which will only prolong your grieving process. True closure can be difficult if there is still dialogue between the two of you. A clean break will make acceptance of the end unavoidable. If he is the one contacting you, consider changing your phone number and email address. Delete him from your social media accounts so you aren't forced to inadvertently think about him throughout the day when you login to your accounts and he's posted an update. If you don't want to delete him altogether, most apps have ways of blocking people, as well. While you may be tempted to do whatever it takes to relieve your feelings of loneliness, you will be further behind in the long run if you rely on something as destructive as these numbing agents. Drugs and alcohol will block your feelings, and put off the grieving process, rather than getting you closer to starting to heal. There is a chance you could develop an addiction, producing another issue to overcome. It's possible you could drive away friends and potential future mates with this harmful behavior.
