Men... 

AIBU to just resign myself to the fact I will never meet anyone and have a relationship again?
Just turned 40, widow, 3 amazing DC but men, ugh.
A guy at work (not who works there but came in to fit stuff) took my number, seemed v keen, messaged a few times and then nothing 
I KEEP getting stuck at this stage, exchange numbers, few txts etc and then nothing 
Should I give up, seriously? I'd consider myself not too bad looking, look much younger than my age, good job, car, independent etc. 
Has anybody met their partner after 40?
