Search Results: friend vs. relationship

Hey guys... I know this is quite full on but I can't talk to my friends about this and I need insight.
I have been married for 3 years and been with my husband since I was 15 (now 30).
He is a pretty big pot head and it causes a lot of problems in our relationship. He goes mental when he doesn't have it and it quite often scares me.. he always says he'll stop but I think that's just something he tells me when I'm not talking to him so I'll get over it. I never nag but I often tell him I just want to run away and not have to deal with this. Im highly sexual and it affects me so bad. He gets stoned and falls asleep every night and I end up having to satisfy myself all the time. I work with a lot of males and I'm attracted to one in particular and we've started chatting on Facebook and I know this is evil but I hid most evidence of me being married before I accepted his friend request. I don't think I'd cheat but I'm craving the attention! Im a good looking girl with a really laid back attitude and I feel my husband doesn't appreciate at all what he has.. should I stay or just be over and out?

So, I have never been the kind of girl to get serious. That's not to say that I haven't, I just prefer casual. I'm good at casual, comfortable with it, even. But I met this boy at university, and well, the first night he drove me home, and slept in the bed with me though nothing happened because I was two drunk. Fast forward a few days and we are hooking up- at first it wasn't great but he improved a lot to meet my tastes. It's been almost a month now and he's dropped the L-bomb and I've met his mother. Unfortunately, he recently got a concussion from rugby and he's been a bit of a bear- not texting, grumpy, etc. He called me from the hospital and I went to go stay with him.
I've met his friends, and the sex is (ball-slappingly hard and) great, and I really like him ( a lot), which scares me to no end. We've decided that we'll "cross that bridge when we get to it," because I told him that I tend to run when things get too serious. I don't know if I want a relationship, but I do want him... He makes me laugh and I'm happy around him, and he's said that he's happy around me. But, I'm worried that we might be cooling off because of school work and is that bad? I just need some clarity, any help at all would be greatly appreciated.

Also: He kissed another girl while still dating his last girlfriend, which worries me, but he seems sufficiently contrite. Another reason as to why I might be a tad hesitant!
