Hello. I know I’m being pretty unreasonable here. Need help to get past this! DBF of 2 years, don’t live together but spend a lot of time ( most nights) my kids grown and away. He has much younger primary ages. I was widowed, he’s separated, never married. The fact he has such a close relationship with his ex is doing my head in. I know it’s better for his children that they get on. No worries that either want to get back together- she has a new partner. It’s just Constant messaging though. They share 50/50. When his children are not with him she messages all the time, youngest doesn’t have a phone. Pictures of what they are up to, ‘do you remember when’ type of stuff. He tends to hide the majority of it as he knows it bothers me. I just think I’m not cut out for it really. But I love the vast majority of our relationship and get on great with his children. And I know that it would be much easier if I was just cool with it. But I’m not.
