Boyfriend and family …

My goal for a relationship was too find a man with a close knit family, I always wanted a big family and to be accepted. I have been with my boyfriend for 2 years and I just don’t get along with his family. His mother and I will get along for a few months then she “no longer wants to get involved.” I do everything for her son, including provide for him because he can’t keep a job. At this point I just don’t know If I belong…. He’s an only child from his mother so I think that plays part in how she treats me. She also always gets involved with his child and acts as If she’s the parent. Within the last few weeks his sons mother and her have been in contact more and she’s constantly believing everything she has to say and demanding her son on when to pick his child up & so on… really it’s just a lot. someone please help ❤️
