Roxana

My ex reached out to give him another chance and workout our relationship this August and we were apart for a year ...... so when we first started talking again on working out this relationship he asked me if I’ve been talking to anyone or had sex I was honest and said No , so I asked him the same question and he said No ...... so we got back together so far so good and I asked him to add me on fb and he said No he blow up on me and making excuses why he doesn’t want me on his fb he also made me feel and think like I was the crazy one and in the wrong but my woman intuition was telling me girl why is he making so much excuses on adding me if he got nothing to hide I asked him that and I started to dig and yes it took me 4 hours to dig up his fucking dirt and turns out he lie to me and betrayed me he was dating and he was sexually active smh after I told him I trusted him with my body and we had sex without a condom and when I showed him all the evidence and proof pictures and comments he said yes I was dating and I had sex with this girl I was with for 5 months without a condom.... I was so disgusted and disappointed in him and myself because the fact he lied to me and I trusted him with my body smh till now I can’t forgive him for lying and betraying me ..... he keeps begging me to give him a chance to make things right that’s he won’t lie again , I tried to give him another chance and forget that he lied to me and forgive him but deep inside I can’t because he didn’t care about my well being he didn’t care if he gave me any STD , he hurt me with lies....
