Boyfriend makes fun of me...

You're right, his behavior is unacceptable. When you tell him to knock it off, you need to be firm, if he starts arguing and trying to blame you just tell him that this isn't open for debate, he will start treating you with respect. Period.

takl to him and tell him how this is making you feel

My ex did that all the time. And at first it was funny and cute. And we laughed about it. Then he escalated it until my self esteem was horrible. I couldn't leave the house without him putting me down at least four times. But here's the thing: I was getting hit on literally everyday. After a while, I understood that it had nothing to do with me being inadequate, it had to do with my ex feeling inadequate. And before you start feeling sorry for him, please understand that it is exactly this cycle which leads to domestic violence. And eventually my ex ended up putting a hole through our wall because he was so frustrated with watching our one year old daughter for an hour.

Men that need to put you down, are not worth your time. They will try to damage you so much that you could never be with anyone else. It is about power and feeling in control of their lives. He jokes around with other people for the same reason: to establish his dominance over them. He says nice things about other girls for the same reason: he wants to insinuate that you don't have that much power over him. You don't need someone like that. You really are better off alone.

Oh, and he won't change. Really. He won't. It will get worse. You may have to see this for yourself to believe it, and I can hardly fault you for trying to bring out the best in someone else. But once you have seen the pattern for yourself, please do the smart thing and leave.

They`re always sweet and complimentary in the beginning lol. Maybe he really I sjust joking around and he doesn`t know you take it seriously and that it actually affects your self esteem. You should talk about this with him so he does know. Maybe he wants to move on too and tahst why he doesn`t say nice things about you anymore. Some people though just tend to take you for granted though and they think they can say ehatever they like and you1ll take it because you1ve been with them for so long. I think you need to sit down and talk to him about this.
