I am a femme lesbian that need to get some things off my chest. I have been in this relationshp for 6 years...?

I am 43 about to be 44 years of age. I have my own apartment but I spend 98% of my nights at my girlfriend house. While I am at her house, all I do is complain, but I won't go home. She has a dog that isn't train so he boo boo and pee pee all ove the house except for the room that I sleep in (where he is not allowed). Then we have a serious mistrust thing going on right now. The both of us have seen other people. She did while we were together and when we separated I had a couple of femme's. I forgot to mention that I am a femme and my girl is a stud. Now, with all these issues we are considering living together. This means give up my place and totally live with her, her son, daughter and dog! When I think too much about this situation, I start having doubt and feeling like I'm doing the wrong thing. I work full time while she is doing Lord knows what because its not keeping the house clean or training the dog. I love her but I can honestly say that I don't trust her. I'm always looking for someone to talk to but I feel like I have the answers to my questions.
