My df's ex-girlfriend is also his oldest son's mother.
I KNOW they have to talk. I have absolutely not issue with them talking all day about their son. I know he's also trying to be friends with her, which I like, because my parents were divorced when I was young and didn't get along at all.
What I don't like is that she texts him late at night. For example, she just texted him, and it's 12:30am. I only know becase his phone is beside me on the table & it lit up.
I'm not making a big deal out of it and I have mentioned it to him once, but its not worth anyone arguing over. But, my question is am I being irrational in not liking that she texts him late at night for reasons not related to their child? I know it's probably some jealousy kicking in. lol.
