Do you think status & commitment are necessary in a relationship?

[say what?]

Me and my 'friend with benefits' lately had a conversation. I was mad at him because he had a girlfriend, I told him that he was so mean and he didn't have any idea on how I feel. He said he was sorry for not being so sensitive about my feelings but he said just because he had a girlfriend doesn't mean I have to stay away from him, he said the reasons why he wouldn't make me as his girlfriend was because 1. he's not ready for a long distance relationship (he lives in different town) and 2. because whenever we had a commitment and had an official relationship, like girlfriend and boyfriend it had never work out, not even last long, we always ruined it (he's my ex boyfriend, we had broken up twice and the longest relationship we had was only last for 14 days -,-) and by being like this (friends with benefits) we wouldn't have a 'break-up' kind of thing.
But as a girl, I feel so jealous whenever I see him twitting (via twitter) his girlfriend with nice things, I mean he never did that to me
What should I do? I really like him, I feel so connected with him unlike when I'm with other guys, I feel so comfortable with him, but I guess he doesn't respect my feelings for him? I have no idea on what to do now...

Always remember the number one key for one or any relationship to be formed is by communication. No communication= no relationship.

So sometimes is best to ask and find out (maybe from other friends) if this guy is really intreasted. Sneaky but it works most of the time.
