:( it would be a long story and I don't think you guys want to read it. I would especially need guys points of view..
Guys, what would you think if a girl that you used to have sex with said hi? Every time we pass we ignore each other because it ended badly, but this was two years ago and I just want to say hi instead of it being awkward. Guys, what would you think if I said hi? Also, I think the reason he doesn't say hi is because when he tried to message me twice asking how I was a year ago, I ignored them. The reason I want to say hi is because I want to be friends with him. He is my first..and only
to your first question... I wouldn't leave GAG as my last resort for answers. I may use it as a resource but I also know taht I can turn to my friends, family, girlfriend etc for advice
as for your specific situation... Stop just saying hi. Strike up a conversation. Apologize for blowing him off, explain why you did it and that it was a mistake. But honestly you did completely blow him off so if I were him I'd probably not be very responsive to you saying hi.
As long as you break it down and not have on long paragraph and/or running sentences, I will most likely check it out and give the advice if I think it would help. I've had some questions that almost took up the character limit (3K) and still got a dozen or more replies.
If GAG is your last frontier there's a major problem in your emotional support chain.
@U: I highly recommend you not bother trying to re-ignite cold tinder but if you feel you must then go ahead. He won't be totally uncivil and may just ignore you. That's the worst that could happen; so just do it without expecting a response.
GAG is absolutely not the first place you come for advice if you have any kind of rational and intelligent qualities about yourself.
