Any insite?..cancer female, pisces male

I've been dating my 1st pisces guy for 1 month & 1/2..
I am so confused...
I don't get him. Is it just me?
Things happened very fast and now we have agreed to slow it down.

We are both fresh out of very bad relationships. I was married for 14 yrs and asked for a divorce, because among other things, it was like having a roomate with benifits and I wanted the happy ending. I jumped into a relationship with a guy that showered me with attention and stole everything from me he could get his hands on. he has a pill addiction..dumped him finally after meeting the guy I am with now and being embarrassed by the story as I told him..realized, what a loser I was with if I was too embarrassed to even talk about him..
He had a similar situation with the girl he had been with off and on for the last 7 years, except he also had the bomb shell dropped that he was not her childs father after believing so all along.
after the 2nd date, he stayed at my house and didn't go home (momma's house), until christmas. we work together and lived together..a little too much too fast for both of us.

neither one of us want to mess up our relationship...it is probably the best one either of us have ever had. we seem to connect on another level. something inexplainable..just there naturally. very conforting..very adult..
three things kinda confuse me...
1) At times he withdraws his emotions for a while and I can't tell if it is something I have done or he is just trying to deal with other things in his life.
2) Kinda embarrassing, but sex. It is the absolute best I have ever experienced because it is so emotional, almost other worldly. He says the same thing. BUT...he has a low sex drive and it is a lot less frequent than i would like it to be..he says he has always been like that and it has ruined relationships in the past. I'm not sex focused, but i have never been deprived either and it gets a little frustrating at times...
3) Total momma's boy (he's 27). I am glad he is family focused, but sheesh...it is a little overboard sometimes... I know that is a line with him I can NEVER cross. His last girlfriend and her HATED each other. Caused a lot of problems with them and I am very careful to kinda stay away from this subject except for giving him all the support I can. I didn't even meet her until day before yesterday for just a few mins at our work. don't get me wrong, I do not feel like I have to compete with her for anything, it is just a little wierd sometimes.

I am 32..lol
He was out on his "own" till recently. His ex and him had a place. I thought they had been broken up for a few months before we started dating, but it was only a few weeks. I had assumed that and when he told me it had only been like 2 weeks..it kinda scared me, i'm not a rebound..lol
it is a little wierd how devoted he is to her. i think he is trying to make up for the time they lost when he was with his ex...
I know you are right about the sex thing..but when it happens...woooooowwww
The withdrawl thing is the big one...he does it until i have just about given up..then showers me with attention and makes me feel silly for ever doubting his feelings...this will probably be the undoing of us, eventually..cause it is a big deal for me. i need to know where i stand..(typical cancer girl..lol)
God do we have the chemistry...make me have butterflies, even now...first guy i dated with green eyes and boy, could i get lost in them forever....

none of that, he just gets real quiet and seems distant. i know that sounds like im being needy, but it is a marked difference in behavior. if he ignored me, i would be gone. it feels more like indifference...maybe im just too sensitive. if i ask him if we are ok, he says yes and acts like he sincerely doen't think anything is wrong.

or haven't pooped in two days...
I hate it when that happens...lol
i really do take it personally, and i have to really work on that..i ended up telling him that i was sorry i jumped to conclusions and i now realize the whole world doen't revolve around me..maybe that is what i am to learn from this guy. he is so different from anyone i have ever been with it really rocks my world..
