I get too attached

I see a lot of posts on here about people being upset and jealous when their friends get pregnant or how no matter how hard they try it's hard to be happy for them and see them and hear about their baby and pregnency. For some reason I have the opposite when a friend gets pregnant I get so excited and want to know everything about it and want to be involved in every part of it and can't wait to see the baby or hear about the appointments. Like to the point where it's too much and I have to distance myself because I care too much about their business and try not to creep them out and be weird. Is anyone else like this. I can't help it and I don't know why. I'd honestly rather be upset and not want to see them.
