I've NC as this is quite outing and a bit embarrassing.
I met DH at university- he was part of a society that I joined. But, there's a bit of a backstory too....
I went off the rails and fell in with a gang when I was 15. There was this guy, then 18, who was pretty serious news in this gang and a well-known drug dealer around the local area. We fancied each other and started shagging from time to time.
After a couple of years, I got myself together, went to college and got accepted to a very good university.
Anyway, I went away and I think we were both thought it was unlikely we'd see each other again. We weren't particularly bothered though we both said we'd miss the great sex (he really was amazing at it).
At university, I met a gorgeous medical student and started shagging every now and then (he was is pretty amazing at sex too). This gorgeous medical student is now my DH.
One weekend in first year when we were still FWBs, his brother came to visit for a night out with DH. DH wanted to introduce me to his brother but warned me he was a bit of a hot-head. When his brother arrived in a ridiculous Mercedes with blacked out windows blasting Vybz Kartel at a million decibels it was none other than the awesome-at-sex drug dealer I'd been shagging for the last year.
DH was pretty shocked but had no right to be pissed off as we were only FWBs. Anyway, we all went on this night out and ended up having a three-some
.
After that, DH distanced himself from me for a while saying he felt pretty weird about the whole situation. That was fine. We both got on with life for a few months. Then we arranged to meet for food one evening and he basically confessed his love for me and we started dating seriously.
It was very awkward at first whenever I used to see BIL but it's been years now, we're all much more grown up and it's (I think, mostly) fine.
