<human>: Condense the text into a few key points

I've been seeing my boyfriend for about 11 months now and we have a great relationship. He has been living with his mother and her new husband since he moved to where we are now for about a year and 3 months. Anyways, his mother and I got along great in the beginning. She would always include me in things. She would buy me little gifts and I bought her things in return. We had no problem chatting about things and I would occasionally spend the night over there. She slowly began to limit my time over so I backed off and gave them their space. Anyways, no matter how much space I gave them, her restrictions on my time spent over would get worse. First it was she can't spend the night, then it was don't close your door while she's over, next it was she can't be in your room at all, finally it was she needs to spend a lot less time here. We are all adults and this was strange to me but I respected her wishes. Now every time I come over its so uncomfortable i don't feel welcome at all. She's been telling my boyfriend she doesn't think I'm ready to be in a relationship and that we shouldn't be together. She once told him that she thought a dark presence was following me around. She also makes subtle digs about me when I'm not around. For example, I spent the day with my boyfriends daughter and when she got home and his mother was bathing her, she wouldn't stop screaming. Her response to him was 'she only acts this way when she spends time with helpmehelppyou'. His daughter is only in town for a limited amount of time and I love spending time with her but his mother is making is somewhat difficult. I still try to be my cheery considerate self around her despite all this so I don't understand what I did to make her dislike me. My last relationships family absolutely loved me. So much so that I still see them almost every week. I would have loved to have the same good relationship with his mother... I feel like its putting a strain on our relationship and I'm beginning to resent her a little. don't know what to do...help.
