Search Results: getting more physical with boyfriend

My boyfriend and I have been together for 4 years and have been planning on moving in together in about 4 months. We had plans of marrying each other, having kids and family. We have had lots of hardships but we are good together. We had to fight for our love with my parents since they are traditionally conservative Asian parents and didn;t approve of my relationship with him because he is not the person they want me to be with. But our love still stayed strong and finally taking that next step of moving in together. Then I found out this morning that he got really drunk last night while being out with the guys (he went out of town for guys trip) and kissed another girl and tried to meet up with her afterwards but couldn't find her so came back to where he was staying. He apologized and started crying when I told him that we can't be together since this is not the first time he meessed up. Just 6 months ago I found out that he was inappropriately talking to other girls, flirting and such but never was physical. He apologized to me then saying he will never flirt with another girl and how much he loves me. We worked it out and he was good for 6 months- he lets me look at his phone or ask him where he is going and we have been doing more couply things and hanging out and such. and now this happens. He feels very remorseful and started crying saying he couldn't lose me and he will do whatever it takes to make it right. But I see a pattern of him talking to girls just getting worse. HE is a very friendly, out going guy and can talk to anyone, guys or girls he will make friends with. I believe that he was super drunk and was no thinking and made a mistake of kissing another girl, but I cannot trust that he won't do this again in about few months. Do I forgive him for being super drunk and give him another chance since we have been together for so long and we love each other? I am leaning towards just moving on, making a break-up since I'm not sure how to trust him anymor

About a year and a half ago I met a guy while my then-boyfriend and I were on a "break". We had instant chemistry both physically & emotionally. However, it didn't last long because of external factors on both of our parts. We've kept in touch sporadically over the past year or so, and recently started hanging out again a few weeks ago.
It was the third time I had seen him since (last week) and we were laying on the couch watching a movie. Next thing I know he's showing me profiles of girls on POF! I was completely baffled. I mean I don't expect a damn commitment from him but come on! I shrugged it off and we ended up in bed anyway (as much as I hate to admit it, it is in fact one of many reasons I contacted him again). He spent the night and left for work in the morning. I, of course, spent the rest of the next day trying to figure out what he was thinking.
Sure enough he calls me during his lunch break just to say "hi" and to ask what I was doing later. I had no plans and told him so, and he responded with "okay so I'll see you later?" (I was okay with this since it seemed that he was more interested in the physical aspect and I'm not looking to jump into anything at the moment.)
When he showed up later that night, he had not only brought treats for my dog (who he knows I adore more than anything), but had brought over food to make us dinner. THEN after dinner we fell asleep together, something that we NEVER do except after sex. This morning he and I went to breakfast at his favorite place, which happens to be extremely out of the way for both of us.
To make a long story shorter, I thought we were doing the friends with benefits thing since he never seemed interested in pursuing a relationship (at least not back when we met). Now he's all about the PDA and wanting me to meet some of his friends and doing sweet boyfriend-y things like making dinner and bringing my pup treats and even opening car doors!
Am I crazy or am I getting mixed signals?
