Obsessions with people

Hi,

1. Does anyone else find that they get fascinated with people they meet and become obsessed with them? I tend to do it when I make new friends and I spend a lot of time thinking about them. I have a partner who I absolutely adore, we've been together 3 years and I really do love him a lot. This obsession occurred when we first became friends a few years before getting together. I've been obsessed with friends since. I made a friend at work who I clicked with straight away and I've started to think about them a lot, as is the pattern with me and new people. I just feel guilty about it, like I'm doing something wrong that isn't fair to my partner. I don't have any romantic feelings for this friend, I can easily recognise it as my normal pattern, but I'm struggling with this guilt that's arisen. I don't know, it makes me feel ashamed that I get so attached to people??
