I've known 'Sam' since we were kids, we dated throughout our teens followed by a brief engagement but we just weren't compatible so called it a day but remained firm friends. I came to view him as a friend far more than an ex.
Some years later I met my now DH and we started a family. Sam remained a firm friend throughout and DH liked him too. He had no issue with us being friends despite the history.
Then Sam met his (now) wife and the longer they were together the less we spoke and he seemed to want to avoid meet ups with friends if I were going to be there at all. There had been no falling out or crossed words.
Then out of the blue one day I noticed he had deleted me as a friend. Confused I sent a message asking if I'd done something to offend him. He read it and didn't respond.
I could only assume he decided to cut ties out of respect for his wife which I thought was fair enough as not everybody is comfortable with their partners remaining friends with exes, although we had known one another for decades and it felt a bit shit to be losing a friend for seemingly no reason.
I later heard through a mutual friend that his father had recently passed away. I wanted to send my condolences but decided against it as I didn't feel any contact from me would be welcome given the deletion and subsequently blanking me.
So last night I got drunk for the first time in almost 2 years (me and DH have had another baby) and dick head here decided it would be a good idea to message him after all, encouraged by an equally pissed mutual friend who was of the opinion that he would appreciate the support 
I wrote:
Hi Sam. I heard about your father and wanted to send you my condolences. I'm very sorry for your loss and I hope you're coping ok. No response is nessecary.
I'm fucking cringing today and think I should have left it well alone because I look like a pest contacting somebody who clearly wants nothing more to do with me.
He hasn't opened the message but I'm sure he's seen it. God only knows what he thinks of me now, messaging him again after he blanked me months ago.
So do I look as much of an idiot as I feel?
