Trying again with more detail.. serious guys opinion's only please!!?

Suddenly my bf of 1 陆 yrs wants to go out with just the guys. but knowing his past, of being a cheater & the tactics he used to cheat on his previous ex like saying he鈥檚 going out with the guys & has a girl meet him at the club. he did this when he & I were friends I would tell him to invite his gf & he would say she鈥檚 working. (he & I didn鈥檛 hook up until month鈥檚 after they broke up. she found out he was cheating)so red flags are going up for me. he swears that nothing's going to happen, he'll never leave me he loves more than any woman he鈥檚 been with & i do so much for him. he's say's when he's out girl's don't pay attention to him cause he鈥檚 short & not the best looking guy. (everyone know's what can happen when alcohol's involved) I don鈥檛 want to nag him or fight with him about it & I know everyone needs space.
so would it be wrong for me to ask him for an open relationship? If not what should I do?
talking to him doesn't work he say's he's changed.
fyi- his guy friends cheat

Yes, I鈥檓 well aware of what I got my self into with his cheating in the past. We were friends before we got together & I helped him get through his last break up. He would tell me how he was getting to old to be cheating & wanted to change. He wanted to find someone to fall in love with & settle down.
Again we have been together for 1yr. & a 陆 & he sleeps at my place almost every night of the week. Guys would you say once a cheater always a cheater & should I be worried? I want honest opinions please this is my first serious relationship since I lost my husband. He knows a lot about what I鈥檝e been through and says he doesn鈥檛 ever want to hurt me. I just don鈥檛 know鈥?

You gotta give him some space, and let him go out with his friends. If you freak out about this he won't be so inclined to give the right of way in your relationship. You two have been dating for a year and a half, and if you can't trust him after that time you really need to evaluate how you feel about him. True he made a mistake in the past, and we all make mistakes, but it's been a year and a half and I think he likes you more then his ex's. So let him go out, and you should go out too. That way you won't be at home wondering what if, and agree to both come home at the same time. That way you both win, and will be home at the same time. I hope this helps.

Anyone can change. Go with your gut feeling, it is most likely right.

Ok, there are a couple ways of doing this. #1 you need to drain him. Yes, have sex with him. Try to get him to go twice. If he goes two rounds and then drinks he will never get it up. Or #2 Does he keep his cell phone on him all the time and keeps the ringer on? If so then call him around 11:30-12am and tell him that you and a girlfriend (or something) are going out and thought that you would just swing by for a drink because your close to where he is. Or #3 Ask him where he is going. Then show up around 11:30pm and see if he is there. IF HE GETS MAD......then he is cheating or is an asshole. You have a right to know where he is and where he is going. You are his Girlfriend and he has cheated once before and probably will cheat again.

Good luck
