Hello... I've been with my boyfriend for a little while but we've known each other for a few years now. At first he was an angel, treated me nicely, etc, but now he yells at me in front of his parents, doesn't treat me right. We are fighting all the time because he does things and then he tells me that he's sorry and he's trying to change because he knows I'm a good girl and his past girlfriends were not-good-enough and that was the way he was treated back. Every time we fight he tells me that he needs me, that he can change... he becomes a different person (a good one). I was not trying to change him because at first I thought he was nice but now I'm just not sure If it's a good idea to keep giving him chances. I don't understand he even tells me he wants to marry me! The awful thing is that we life together because his stepfather is my cousin (just temporal 4 one or two more months). Advice please sometimes I feel I'm going crazy.

What is it you fight about ?

Are you living together?

When did he "change" to start yelling at you?

I'm not very sure when he changed. We fight about how he treats me because he knows it's not right. And yes we are living together in the same house but in different rooms, I want to leave the house already but I just can't (money problems). Idk I treat him so nice and I don't want to change because that's who I am.

He might have a behavioral disorder, and he is asking you to stay with him not because he loves and respects you (he would not be offensive if he does love you) but because he panics when he thinks that he will be alone and he would need to find another girlfriend. So it is mere just a fear of being alone and low self confidence.
If you have another place to stay, leave him and get a new start in new year. I've been in this situation, so my advice is-GO!

He wants to change, but someone like just can't without professional help. Sometimes, people depend on a girlfriend/ boyfriend relationship to ease their problems. U can either suffer out of Ur own sweet heart or be tough and put him on the right path and leave him to his help meaning u find a new man
