A little background here I (M33) was left by my now ex wife (F35) a couple years ago, she was cheating on me with an older married guy (they are still together, she thinks he’s divorced but he’s not) and it has obviously been a pretty rough time for me. In this time I have found a great new relationship with an amazing woman (F33) who makes me feel more loved than I have ever felt besides my daughters (8,4). My ex’s relationship is very secretive, I don’t pry but my daughters tell me he’s over at their house quite a bit but in the past my ex has acted very strange towards me (ex randomly hugging me or asking for hugs, calling me late at night and saying she feels like she ruined our kids lives, would have done things differently, sending me pictures of our girls/family from the past) and I have told her she needs to stop this behavior. She will randomly come to my house to try to see our girls and my gf has now had enough of this and came out and introduced herself to my ex a couple months ago, they have not had contact since then, that is until this past weekend. I had my girls and they both had hockey practice and I brought my gf along, my ex showed up and completely ignored my gf, but tried to converse with me the entire time. I was giving her short responses but wasn’t being disrespectful. She then found any reason she could to berate me in front of my gf and the other parents on the team. I didn’t let it get to me but the next day, when she came to hockey, she sat down in between my gf and I, which I assume was to make us uncomfortable, which it didn’t. We wanted to find a better seat so we got up and left and like always she followed us, she’s not open to talking about these situations, she just seems to want to be in my area and if I’m not paying attention to her she wants to fight. Any suggestions on how to handle this when it happens again?
