Well two years ago I met my ex-boyfriend & we've been on & off & even at certain points we stopped talking but always at some point ended up getting back in touch with each other. Just last month after three months of not speaking at all he inboxed me on Facebook and was just basically asking me how everything has been going in my life so far. The next day he asks can he come over to my house being as though he now works close to my house and I agreed. Prior to this I had looked on his Facebook account & it said that he was in a relationship so when he came over I straight up asked him from the beginning & initially he says "yes" & I replied "does she know you're over here?" & he says "no" & I'm just sitting there confused so I ask "are you serious?" and he says "no". Eventually one thing led to another and we had sex. As I was walking him to the bus stop it was this voice in my telling me that he's lying so I check his Facebook again & it still says he's in a relationship with this girl. The next morning he texts me & I never replied. I was on the phone with my friend this same day & I was telling about everything that went down & she's like "matter fact he does have a girlfriend Kevin(her ex-boyfriend) told me(Kevin & my ex are friends.) I call him & he's still lying so he apologizes which I know he's only sorry because he got caught. After that we stopped talking again & then a few days ago he texts me & we were talking & he sends me a text saying he's sorry about everything that happened before & he just wants to be in my life & for me to comfortable enough to call/text him for anything. Later that day he comes over & we just have a long discussion about how things are & we again got on the topic of his girlfriend & I just was like " I don't even want to know if you have one or not,just don't tell me". He says he's going to tell me anyway and says they broke up. Idk why but I believe him this time.. Am I too gullible? Should I just leave him alone??
