Am I wrong for wanting to leave my boyfriend?

The day that my boyfriend went to jail his friend called me and asked for his belongings , but i told him that i hadn't heard fro him and he was gonna have to get them from my boyfriends mother. He immediately blew up saying b imma f you up when i catch you and your probably the one who called the police on him. We both argued back and forth about blaming each other then he finally hung up.The next day down at the city courtroom i ran into my boyfriends mother and his ex-girlriend. His mother gave me a look like what the hell are u doing here and rolled her eyes so i took the hint as she didnt like me nor wanted me there, so i gave her the papers that he asked me to give to his lawyers and left cause i felt uncomfortable. Every court date after that his mother continued to make me feel uncomforable and the ex began sending me msgs through his facebook telling me he doesnt like me keep ur petty money u sending him, stop trying to get in with his family cause his mother doesnt like u i mean i could go on for days but im not. His mother even told the ballops that she was his girlfriend. When i talked to him i asked him what reason did he have to tell her all those things and that he just might as well be with her cause i was done and tired of his mother and her persona towards me. Now i didnt go see him cause i had unpaid traffic tickets but i found out that i could still go see him. Now i was spent well over 3000 in a 5 month period. But after the girl had told me all those things i didnt trust my boyfriend anymore and i stopped everything that i was doing to help him. I still visited him but i wouldnt spend any of my money on him anymore. But one day i went to visit him and the girl was there, he told her to leave and told tme that he couldnt have any visits. After she left i went back up , he told me some bogus lie and i went on about my day. Now his mother gave me the impression that i didnt belong anywhere near her son and that he and his ex was together and he didnt make it no better cause he never took up for me. Everytime i told him what the girl and his mother were doing he would say that i was lying his mother dont have a problem with me and im trying to use that for a reason to leave him. So i said the hell with all of them i talked to him occasionally but kept my distance cause something was just telling me that no one really cared for me to be apart of his life. Now when my boyfriend first got out of jail we argued alot cause i stopped doing for him and i told im to thank his mother and the girl for it and he told me that he did thank god for putting the girl in his life cuase she was there for him and he bragged about how loyal she was. But i kept trying to tell him that his ex and his mother acted that way so that would be out the picture and it worked cause i got tired of it. So everyone else thought that i left him for someone else he never told them that it was because his ex family picked on me at court and his mohter didnt want me around. My boyfriend still to this day have never thanked me for spending all my money on him and coming to see him. His mother speaks to me now but i just dont like her i dont even go into her house just so that i dont have to talk or say hi. Its funny cause now she know i dont like her so she speaks now i wonder what she's up to this time. I just dont understand i ve tried to leasve him so many times but he wont go away so it makes me think he do love but i just wnat him to understand all those things they put me through and for him to ga away
