Why is he doing after we broke up?

he didn't change it because he knows that you know it. since you still have access to it then how about you delete his account lol.

Ok, so you miss him and you want to see what he's up-to, so for better or worse, you log into his Facebook and check-out what whom he's been contacting. Coincidentally you then get a message from him trying to mess with you. Then you want to use these two incidences as leverage to get re-involved with your emotionally abusive ex-boyfriend.

I can't tell you how to live your life, but my advice is to let him go. You broke up for a good reason. You broke up because he was hurting you. Take pride in being strong enough to do this and know no matter what happens, no matter how much he 'changes' or misses you, know that the end of your relationship was for the best. It is better to cope with the loss of your boyfriend than to get back into a relationship that will hurt you in the long run. Find support in your friends, then, when you think you are ready, find a nice guy who will support you.

That's my advice. It takes a lot to let go. I'm glad you were strong enough to brake up with him. Congratulations.

Now, don't log into his account again. De-friend him or do whatever you have to do to avoid checking up on him. It will only make you second guess yourself.

Sounds like he is just seeking attention, trying to make out that he is enjoying the single life. The message he sent was trying to make out that he was sending it to someone else and have mistakenly sent it to you.

I don't know the full situation or him in general so this is only a guess. I think you should just ignore him all together and not check up on his Facebook especially using his password. He is definitely still being emotional abusive but just in a different way.

Save yourself the pain and ignore anything that comes along your way.

It's normal that you still have feelings and curiosity about him. You just need to be strong.
He's doing that stuff because he's trying to cope with being hurt. He's using sex to cope with his feelings.

You really need to get off his Facebook account. What you're doing is both unhealthy and highly illegal. If you don't think you can resist, you can change his password to something you don't know, then he'll have to reset it. Just type in a bunch of random letters, copy it into the confirm field, then log out. You won't be able to get back in.

And ignore him so he can't send you messages. There's no use trying to stay friends with an abusive guy.
