TIFU by trying to find love online. I have recently gotten out of a long term relationship and since I am a single mum and been out of the game for a while I thought why not give online dating a go ? I set up my profile and so far so good. Until I see this cute guy his photo is a bit hard to see but his profile looks promising and he looks cute . I never really am one to say hi to people first but this one time I did. I message "hey, how r u ? Xx" I get back "hey long time no see" I'm thinking , oh shit... I look closer I still have no idea who it is. I reply "umm do I know you ? " turns out it was my ex from high school and it was the worst relationship ever... He looks so different I didn't even recognize him ! He asks for my number and I have no idea what to say. So embarrassed I told him I didn't want to talk to him and blocked him . He was so horrible we dated less than a month and he cheated on me and lost so many friends coz of our toxic relationship. I can only imagine him laughing to his friends about how I hit him up on a dating website...
