Should I stay or should I go ?

Im a Pisces woman who has been dating a scorpio man for abt 6mths . Our lives are mirror images of eachothers and when 2gether we are great . However, we have both been badly hurt in the past , and find it difficult 2 trust and are both very insecure ...... he shows me very lil emotion , where as I am very emotional ...... recently he told me he couldnt give me wot I wanted .... ( wasnt sure wot he meant by that coz I didnt even knw wot I wanted out of us ! ) ... so i thought mayb it was just his way of sayin he wanted out , so I finished it ....... abt a week later he txt me and we had a friendly chat , he told me 2 crack on with my life and that we should stay friends ...... so again as hurt as I was , I did crack on with my life . Another 2 wks went by we send the odd txt , then out of the blue he told me he does have feelins 4 me but not as strong or as deep as the feelins I have 4 him , and that he is frightened that hes gonna end up hurtin me ie other women . Which I thought was great of him 4 bein honest .So AGAIN i thought ok move on with my life 3weeks later I arranged 2 go on a date and BANG ! ........Jealously ?? OMG .... I never realised how jealous he was. A friend saw him and told him I was goin out on a date and he kept askin her question after question , he then contacted me and done the same , hes been makin sarcastic comments , even 2 the point of puttin me dwn which surprises me coz we ended on good terms. I went on the date as I thought I aint gonna have him dictatin 2 me who I see or wot I can do , but abt 2 days after I had the date he wanted 2 meet which I did and load and behold I had another bombardment of questions , I told him I still had feelins 4 him and that I was findin it hard 2 walk away frm ( I could kick myself 4 sayin it now tho ) ..... then he came bk with I do and I dont want it ???????? ..... When I asked wot he meant he said hes 2 frightened 2 committ bcoz he knws that men r attracted 2 me and I may find something better ( im 13 years younger than him ) ( and im no super model !!) ....... so now im really confused .......... I do cut my losses and go ..... or perserve with him and his insecurities ????? PLEASE HELP SOMEONE
