Relationship advice from some guys please!?

wow good question well it been said that always always trust ur gut feeling it usually never fails, int this situation its hard to give an answer because no matter the out come it changes things. but in reality i had this similar situation i started a new job at an office n my office space had an empty desk little to my surprise my ex was the other occupant i told my girl at the time what had happend n that ive tried to see if i could be move she was mad at first thinking that some how i wanted to get hired there of of her but its hard not to talk to an ex when u see him have u done it i mean he could of call u n tell he ran into her n see if it was ok for him to chat with her n for how long an hour trust me i have never talk to one of my ex for that long not even if i know that talking to them might get me laid so if it was closure he wanted it wouldn't taken that long to talk. bottom line sweaty if u approach him he will recent u telling u how u don't trust him that he loves u n hes working hard for both of ya blah blah blah don't want to sound like a dick but its true, two ask ur self y did they brake up in the first place, n like i said trust ur gut its better to find out know that later on it might bring u close but it might just tear u apart ask ur self does it really matter that much to u just to belive him is ur love strong enough to just keep quite n forget what happend i wouldnt yes it might hurt but its a short hurt it passes n u forget n u live on
