Happy to be told I'm being unreasonable, I just wanted to get peoples perspective on this!
I've been with my boyfriend for around 6 months although I've know him as a friend for years. He's got 2 DC with his ex, 15 and 18. They've been split up for 10 years. I've got one DC with my ex, who is 17.
He has his DC 50/50 although it actually works out that he has them more.
I see him around 3 times a week. The last few weeks we've been seeing each other earlier in the evening due to a change in working hours. Every time I've seen him in these past few weeks his ex has rang him not long after I've got there/he's come to mine. I can't hear what she's saying but it's definitely about their kids and they're talking for around 5 minutes.
I'm guessing I've only noticed this recently as I've been seeing him earlier. She seems to ring when her new-ish boyfriend isn't with her (please don't ask how I know this as it'd be outing!).
Do other people speak to their kids other parent this often? It could be that I just feel a little uncomfortable as I don't have that kind of relationship with my DC's Dad. We are amicable and always have been but most contact now DC is older is done between them and their Dad, there isn't much need for me to speak to him and certainly not 3 times or more a week.
I'd be interested to know peoples thoughts!
