I hope that I can get some advice from everyone on this page. First, a little history of my ex and I. We are agreeing on joint custody of our kids and so far have been civil with each other up until recently, We split up at the end up 2016, she continued to live in the house that we had and moved out around the end of January. When she moved out, she had her boyfriend, that she been dating for about a week or so move in the same day, which she did not tell me about for a few weeks. Keep in mind that we have 2 minor children, 4 and 1 at that time. Also, our youngest is not biologically mine (her biological dad moved to a different state) we had split up in 2015, she got pregnant and I took her back at the beginning of 2016 to keep our family together. Anyway, she moves out and has her new boyfriend move in that she's been dating for a short period. For the best part of last year, I remained single due to the fact that I was content with not being with anyone and wanted to work on myself. Since last September, I started getting on with my life and reconnected with a girl that I have known since we were bout about 14. As soon as my soon to be ex-wife found out that I had started talking to her and dating her, I feel like she has done nothing but try and control aspects of my life. I feel like she tries to manipulate me by using the kids as leverage now that it has been brought to my attention, before I was oblivious to the way that she talked to me and tried to be respectful of her because she is the mother to my kids. She has said numerous times that she doesn't want the kids around her, and constantly checks up on the kids whenever I have them to make sure that I am not around her. even though she has lived with her boyfriend since she has moved out, and is expecting her third child. Not to bash on her or anything like that, its her life and she can do what she wants with it. But I ask myself, where does the respect portion come in for me? she never thought about the way that I would feel if she had another man move in and be around my kids, nor having the youngest refer to him as dad, even though I am biologically not hers I was there for her being born and signed her birth certificate. She's constantly in my life and trying to know what I am up to..me or my gf can't post anything on social media without her asking what the post is about and trying to start drama. Its to the point where I am tired of holding my tongue and will put a stop to it. If I don't do it now it will just continue. It has gone on far too long. I understand that she is their mother, but when you have your friends creep just to keep tabs on me and send you screenshots of posts, its getting out of hand.
