I met my DH when I was around 16. We were great friends that developed in to a relationship. A few weeks after we got together I was introduced to his best friend (BF) and had butterflies when I met him.
DH and I stayed together through Uni and then moved to a place where his BF was also living. We had several drunken nights out in which he tried to kiss me (I know, not a great friend but the chemistry was strong!) which I turned down. At the time the BF and I both worked in crap jobs so would spend hours on email to each other, chatting about all sorts and even met up without DH for coffee etc (DH knew and was happy we were friends.)
Then, when we were in our early-twenties we ended up all living together for a few weeks. At this time DH (not DH at the time) and I were going through a rough patch and BF and I were up one night, setting the world to rights and ended up kissing. The next day DH and I broke up, but still remained friends (he is and always has been my best friend.)
BF and I were then living in different towns and had a relationship in which we spoke on the phone and met up a few times. He told me he was falling in love with me and I felt the same about him. These feeling had been there now for nearly seven years. We met up one day and decided for this to ever work we would have to wait. ( DH feelings, lots of shared friends etc)
Anyway, time went on and I realised how much I missed DH and BF met his now wife. I told DH about us having a fling and he accepted that for us to be together he would have to leave what had happened in the past (he's an amazing, non jealous man.)
DH and I married a few years later and we are happy together. I fancy him still, he is my best friend, an amazing Father. Everynow and again we fall out but we've been together for nearly 17 years and still have a relationship in which we can stay up until the earlier hours of the morning drinking wine, listening to music and talking.
If you are still with me, then thank you! My AIBU is that I can't let my feelings for BF go. When we meet up there is a huge spark between us, last time we met we sat in a large group of our friends on the corner of a table and chatted to each other - I felt so alive. The sparks are the same as when we were 16. Fortunately we live a long way apart now, so don't see him that often but I do go through periods in which I dream about him every night.
I would never leave DH and DD as I love them both dearly and he has a DW and lovely children but sometimes I wonder whether we should have followed our hearts when we were younger.
