Hello. I have been there too. My bf of 7 years has 2 kids. It was hard. We went through a lot.

I left him but not because he was a parent or had kids. I knew his situation from the start. I loved him and respected the fact he was a good dad. Having said that - he would never answer the phone when we were just us intimate. There were times when his kids came first and times when i came first.

From what u r saying i think there is a deeper issue. She feels insecure. The phone is a representation of your other life.

The fact that u say she wont understand is agrivating. Maybe you should not be so arrogant... Maybe she understands but feels insecure and threatened... Talk to her. Show her u care. Because from your post you clearly do.
