Ever thought "Why couldn't I marry that person...."?

I have a good husband, he is very intelligent, earns well, very tolerant, patient, etc..when I first married him it was exciting..I mean I was attracted to him..Its been 2 years...hes very patient and tolerates however I am and loves me for who I am...Even i do like him But throughout these 2 years..if I come across other guys and i happen to like their style or way of charming or talking,, I get hooked onto them..My mind is so wandering..Then I end up thinking "Damn that guy was soo sweet and nice, why could I have not married him.." and I keep regretting... sometimes I am soo picky on my hubby's small habits..like if he keeps touching his face, Im like dont do that..or i tell him dress like this, sit like that, etc...Cuz i want him to be more manly, more of what i see in another guy whom I feel attracted to...For example there is this guy i met 2 months ago and he is sooo sweet, the way he talks is so charming, and hes damn good looking..he likes me alot and says wish we could have met earlier and married...But its like hes about to get married and im already married but I sit and feel sad always thinking, damn Why didn't I meet him before?? :-( I easily get attracted to other guys, My mind is feeble like that.. and then end up feeling sad and not giving enough to my husband..How can I get rid of these thoughts of attraction and regret whenever I meet someone who I end up liking and just be satisfied and happy with My husband??
