INPUT ARTICLE: Article: Think about what made you fall for him in the first place. It could be his looks, personality, or a combination of the two. It could be that you're not even attracted to him and there are other reasons why you're pursuing himlike a vulnerable point in life. Understanding what attracted you to him is the first step to letting go of him. Finding the source of your feelings is also a step towards getting rid of feelings of guilt you may be experiencing. Take some time to reflect on the emotions you're experiencing. Remember that nothing you're feeling is wrong or bad. It's okay to still be in love with him, to be angry at him, or resentful of his girlfriend. Deeply thinking about the situation will help prevent you from acting out on your emotions. Write down your feelings about the situation in a journal. You may still be tempted to be with him. Accept that you need to move on from him. He has a girlfriend, and it is not you. This is difficult to accept sometimes, but you won't be able to get over him until you do. Keep in mind that he may not have a girlfriend later down the road. You can't be with him now, but that doesn't necessarily mean you won't be with him in the future. Even still, move on in order to better your own life. If you have mutual friends, it may not be a good idea to talk to them. Talk to friends and family you trust about the situation. They can listen to you and offer feedback. Even if you don't want feedback, vocalizing your thoughts will help you come to terms with the situation.

SUMMARY: Figure out why you're attracted to him. Reflect on your feelings. Accept the reality of it. Reach out to friends.

INPUT ARTICLE: Article: Only use a sturdy ladder to climb up a tree unless you have extensive experience climbing trees. Have at least one other person with you if you're going to go up after the cat. Your helper can warn you if the cat moves, and call for help if you fall. If you are determined to actually climb up the tree after a cat, you should always use safety equipment so that you don't get injured and make sure you have someone else with you in case of emergency. Make sure that there is nothing that would increase the danger if you happen to fall while climbing. Also make sure you have a sturdy ladder. The last thing you need is to get injured while trying to help a cat get down from a tree. Whether you are rescuing a cat you know well or one you have never met before, the cat will probably be scared and may lash out. Long sleeves and gloves will protect you from the claws and teeth of the cat, and they will also give you a better chance of holding onto an agitated cat once you reach it. It's best to hold the cat by it's scruff as it is easier to hold them and it puts them in a trance. Don't allow it to escape before you have put it inside the carrier or get a good grasp on it. Stay calm; if you panic, then the cat will react badly and may not allow you to grab it. You can, for instance, put it inside a cat carrier and lower it to the ground with a rope. The cat may be in shock from its traumatic experience, so make sure it is healthy before letting it go.

SUMMARY:
Go up the tree to get the cat if all other methods fail. Check the ground around the tree before you begin to climb. Put on long sleeves and gloves before going up the tree. Grab the cat and hold it firmly after you reach it. Be gentle yet firm with the cat. Place the cat inside something to make it easier to get to the ground. Climb down and then check for any injuries to yourself and the cat.
