Summarize this article:

Don't ask him to change for you. No one is perfect, and if you're in a relationship with a guy, there will be things that both of you need to fix and compromise on. None of these things should include a dramatic change to his personality or beliefs, though. Be friendly with his friends and ask about his family. By showing an interest in the people he cares about, you demonstrate that you are serious about being a part of his life. You don't need to be best friends with his friends, but it helps if you can tolerate them well enough to spend time around them when necessary. Try not to get too close to any of them, though, since you might spark some unwanted jealous and suspicion. If he's not on good terms with his family and doesn't have much interest in talking about them, don't push the matter too much. Bring it up every now and then, but wait until he's ready to start talking before talking in any depth. There's nothing that says you need to love every hobby he loves, but you should at least take enough interest in it to either try it or let him talk to you about it. If he invites you to try his hobby, give it a shot, even if you know nothing about it. You may choose not to continue with it after that first try, but at least you'll know enough about it afterward to understand him when he starts talking about it later. Offer a positive, flirty remark on how great he is when he least expects it. Flattery can be a powerful tool. Make sure that your compliment is genuine, though, and not sarcastic. Compliments on his appearance can be just as effective as compliments on his personality or abilities. Mix things up a little. When you meet him after work, you might lean over and whisper that you couldn't stop thinking about his dreamy eyes all day. The next week, you might casually remark that you don't know anyone else who can tell as great a joke or story as he can. When the two of you are together, let him be the man. This doesn't mean that you have to be completely submissive, but it does mean letting him take the lead and showcase a few traits associated with his traditional gender role. If he holds the door open for you or offers you his jacket on a chilly night, for example, you should accept the gesture. Be a safe place for him to fall. When things go wrong, let him know that you will be there to support him emotionally and without judgment. Conversely, you also need to give him space. You may find that he needs more personal space than you do. If he needs time to be independent or time to deal with his issues alone, let him have it without making a big fuss over the matter. A guy is more likely to go crazy for a girl when she lets him see that she's crazy for him, too. Pay attention to the things he says and does, then regurgitate this information later on to prove that you were listening. For instance, if he tells you about the pet dog he had when he was 12, you might bring it up in conversation later on. A simple way to demonstrate that you pay attention to him is to remember some basic facts: his birthday, the names of his siblings, and so on.
Let him be himself. Love his loved ones. Take an interest in his hobbies. Compliment him sincerely. Let him flaunt his masculinity. Support him without suffocating him. Pay attention to him.
