I don't mind you asking!
Most revenge boyfriend before current lovely one...
Last year, late Jan, we'd been together over a year, we went out for dinner with his family, came home, had sex, and for the first time he told me he loved me. A week later (week before Valentine's) we'd been swapping photos of bad Valentine taxidermy, laughing at rats holding hearts. Check out eBay - there are some awful ones!
Neither of us "do" Valentine's and had been through one before - so no big deal. But (I think?) it just focused him that I wasn't the one... and a week before The Day he texted (yep, a text!) "I'm not feeling it for Valentine's - could you handle being friends?"
I actually called him and said "I'm actually only 95% sure I've been dumped?"
We're still friends! 
In fact yesterday I texted him "happy dumpiversary" 
But the other one broke my heart! Years ago. Love of my life - well, I thought 😉
We'd had this on/off thing. Basically - me hanging in for crumbs. He wasn't seeing anyone else, just wasn't into me enough and wouldn't make time, and we both said we were too busy for a relationship (me to play cool girl
live and learn!)
So Valentine's was coming up and I didn't want to get caught out, but didn't want to scare him off either. Decided to get a card and if I got one from him was planning to text "got yours to hand deliver... 😉"
No card in post from him. Phew. Didn't embarrass myself.
Get a call next day, he'd called an ex on the 14th, met up, got back together, we were over. I was 😳
Three days later... His card arrived at mine. Totally wrong post code, post office note written over it.
We're friends now, 15 years on. He told me he was gutted I didn't respond/wasn't interested and went running into ex's arms for consolation! In retrospect he was a total headfuck and I'm so glad I finally saw that
But at the time I was all "thwarted love for sake of a postcode" 
So - sorry for hijack, but yeah - I don't have a good history with Valentine's!
