I split with ex about 6 months ago. He's a shit bag I just never realised at the time. He comes to see the kids once a week. They are both toddlers. He just bounces them about a bit talks to them. Plays with them from the chair he's sitting on stays an hour or 2. Does not do any parenting . Just the fun bits. I have stayed friendly to him because I don't want bad vibes for the kids. When messaging me about the kids he also ask how was my day what have I been up to bit of general small talk. But he also sends kiss emoji hearts and I love you type. And he sends messages like "i know you still love me" I reply things like you wish..fool and things like that. I have older children that are not his.my 15 year old went out with him to pick up a takeaway a few weeks back. And he said don't say anything to your mum. But I think she still loves me. Because of the signals she's giving. As far as I know I'm not giving any. So do I need to distance myself from him?
