depends how long you were dating and how long youve been broken up but if you guys dated for 3 months and he hooks up with her 3 weeks later, seems scumy to me
and on a serious note you should try sleeping in the spare bedroom more i know you get scared ****less but maybe after a while you guys can really connect no homo
proving its yours and sueing seems like to much work for 40$, slandering the website giving negative reviews sounds better as far as work/payout is concerned
