I have namechanged for this as am embarrassed and confused. I am bisexual and have been with my female partner for 7 years. I am 32. I have a female colleague who is 10 years younger than me with whom I have always got on well, despite the fact that we are quite different- I am very girlie and emotional whereas she is quite reserved and has a very dry sense of humour. I would describe us as quite close friends.
Lately I am worried that I have been thinking a lot about this girl. She has had a rough time in her personal life lately and has talked to me about it a bit (although we have another colleague to whom she talks more). I am constantly thinking about her and whether she is ok. More worryingly, I am quite obsessive about what she is thinking about me, whether she is annoyed with me etc. I even get jealous when she talks more to my other colleague than to me.
I'm really concerned that I am developing feelings for her which are not normal. However, I don't think about her sexually at all (the idea makes me cringe a little) and I am having real difficulty working out why I feel this way. I would love to stop, as it is taking up a lot of my headspace and I feel weird about it. It is also affecting our friendship, as I find it hard to relax around her, and my relationship, as I am constantly thinking about her and not my DP.
It's driving me nuts- please help!
