Can I just vent a little bit

So I decided to leave my ex because he was very abuse and try to manipulate me a lot . He have not try to see my kids but yet keep stocking my old house because he was trying to get back together. Not once Mission our kids as in seeing them and spending time with them a few months goes by and this man got a new girlfriend and every but yet he continues to stock me and now my new boyfriend on all social media. I went to his new girlfriend to see if she can get him to leave me alone but y’all know what this bitch said (excuse my language) are you just mad because he left you alone with two kids to take care of and he is happy with me and my son . Y’all just don’t know how quick I wanted to go threw my phone to beat her delusional ass cause if he is happy why is he even thinking about me and my life and trying to ruined it . I’m just so sick of my kids father and his family keep stocking me and it’s not even topics about the damn kids it’s about me and him something I don’t even want back a relationship he will never get back .
