Hi reddit! I just got dumped by my boyfriend of 16 months yesterday. I was really happy in the relationship and all of this really took me by surprise. 

I went to talk to my best friend for comfort because I was (naturally) feeling confused and upset and she immediately told a guy that she knew has had feelings for me for several years. This guy, I'll call him A, reaches out to me and starts asking me to go on a date. I feel uncomfortable with the idea of going out with somebody so soon as I think that I need to give myself time to come to terms with what's happening in my life. 

I told him I didn't think I could do it, at which point he began telling me I was stupid for ever entering in my last relationship and that my ex never loved me the way this guy does, or at all. I feel like this is a little too manipulative on his end, but also a pretty disrespectful thing to say. He's now telling me that if I don't date him, I will regret it and that he will appreciate a girl like me more than anyone else will. Am I right to think that I need time to find myself right now or am I just being a frigid bitch? 

I'm feeling lost. This isn't my first serious breakup after a long-term relationship, but the difference with this one is that my feelings were/are much stronger and that I can't look back and find obvious flaws in my ex. How do I deal with a breakup like this? I've thrown myself back into running which makes me happy, but what else can I do to get over this faster? (Or is it naive of me to expect that there's some trick to getting my shit together as soon as possible?)
<bot>: got dumped and now somebody else is trying to date me, but I'm not sure that it's a good idea at this point because I'm not over my relationship that just ended.
