Regular on this board but NCed because I don't want this post to be associated with my regular posting history. I am in real need of advice.
I am 35 and have been dating a great man who is madly in love with me for 1.5 years. Our relationship is comforting, supportive, serene and loving. He is a great partner to me and wants to build a life with me. We talked about moving in together last March. Then after seeing a few places, I told him I didn't feel ready to take that step and he agreed to put the idea to rest for a while. He is now talking about seeing some places after the Summer to move in together in Autumn. I know he is eager to take our relationship to the next level.
However, I have a mad crush on a colleague I work very closely with. From the day we started working together 2 years ago, I felt like he and I had a one-in-a-lifetime connection, we are so alike and understand each other in ways no one else does. I cannot get him out of my head, I literally think about him 24/7 and fantasize about an imaginary future together. My feelings have intensified in the last 6 months.
He is single and to be honest I think he might also be attracted to me, just based on the vibes that I sometimes got from him. Of course none of us has ever crossed that line because 1) we work together and 2) I am not single. We are very friendly but absolutely professional at work.
So my conundrum is: what do I do? Do I move in with my lovely partner who wants to build a life with me? Or is the fact that I have this other crush an indication of the fact that I am not happy with my partner? I cannot make sense of my feelings, I don't want to be unfair to my boyfriend and I am so confused.
Thank you for your advice
