Scared of dating.

like, when I get guys that say they like me, find me pretty, like flirting etc.. i just dont believe it.. because I'm sure he probably messaged 30 other women on there trying to flirt and said the same thing.. I just... feel like I can't date.. ever....not online no... i feel its fake.. online.. in real life if a man comes up to me in a bar.. it feels more real.. like he didn't browse other women.... I want true love.
