I do or not!?

My story: Im with my boyfriend for 6yrs already, I'm 27 yrs old, we both are just so opposite esp the way we think and bin thru a lot but no 3rd party, but basically still together. he now already ask me to marry him and of curz i said i do. while the big day will be few months from now, sometimes when we quarrel i always think if hes the right guy, im praying GOD to give me a sign that if hes NOT the right one he would bring someone in for me before it is too late..I have so many problem with him that i think i can handle it bcuz when im already his wife, we will be staying at his family house and i dont feel like it : * Hes not thoughtful enough, h'es not sensitive (but very sensitive when it comes to other like if hes friends says he seldom go out with them for a drink, its always what OTHER think,) those kind of stuff. . hes explanation was "ur my girlfriend i expect u to understand me, bcuz i know my friends/officemate won't)....i even encounter he hit me unpurposely due to our quarrel, because sometimes i nag too long. He's a hardworking person, but always have a doubt that when in time he earns a lot already i think his attitude will change. he dont find effort to know whats on my mind, what i feel, even what i like to eperience with him, FOR SHORT, hes a simple guy if hes with me just want to hang out at home..but Im the kind of person who is adventurous and like to experience things with HIM like go clubbing, just for fun. but he doesnt want to becuz he dont like pop musics. I have to tell him personally what my needs and wants before he will ACT on it, worst sometimes he even forgot what i said. i find it really hard if im just paranoid or something that I just look all the negatives in our relationship OR im just hanging on because of the years we spent together. I even tried to cheat but I can't. hope somebody can analyze whats the problem in our relationship.

take counseilling with him,personalities are very different,you should be confident about him before you tie the knot.
