My friends DP has a 5, 6 and 8 year old from a previous relationship whom he hasn't seen for 3 years. His ex stopped contact, he hasn't fought to reinstate it. My friend has a 2 year old with him. I can't help thinking he's the same age her DPs youngest was when he stopped having contact and that if they split its likely her ds will be abandoned too. She acknowledges that this concerns her too. I told her I wouldn't be with my DP if I thought he were incapable of abandoning his child(ren.) I appreciate I may have been unreasonable to share my opinion, but that isn't an unreasonable opinion to hold is it?
