In one sentence, describe what the following article is about:

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