I recently gave birth and found out today that my husband has been chatting online with all of his exes these last few weeks. (he hasn't been intouch with them for years). He also failed to mention to them that he is a new dad. When I asked him why, he says he doesn't want to hurt them. Am I unreasonable to feel upset about his behaviour?

First, congratulations! Welcome to parenthood! At this point, I believe you have all the reasons to feel upset with the situation and yes, most importantly with his behaviour. But, this doesn’t mean that you should worry too much. It’s not good for your health especially that you just recently gave birth. My thinking with this situation is that (and probably yours, too) to be fair, I could consider getting in touch with old friends as a normal gesture. But how come he happened to be chatting not just with his 'old friends' but more specifically women whom he had past relationships with? I could consider that fishy but I opt not to. Why? Because it is still best to have an in-depth conversation with him. Yes, Hui Qui could be right that maybe these women have been trying to conceive but still haven’t gotten any success or that these women have problems with their own families that announcing this good news could probably make them feel worst all the more. Best thing to do is to be always think of two side of the story, and that means hearing his but let him be specific. Communication always play a great key in relationships and that is what you should be continuously building.
