Hey fellow podders... juz nid some advice...

i've been engaged for 1 1/2 years n myte be getting married next year... my problem is my fiance is too protective n get jealous over small things... like recently we went overseas wit a few close frens n while we were shopping we saw my ex.. n my fiance being the over jealous type kip on looking at me to look at my reaction wen we saw my ex... after my ex walks past us my fiance kip on asking me y r u so happy wen u saw him? but the truth is i was not smilling at all...through out our shopping time he kip on asking me bout my ex till we reach our hotel rooom he juz wont stop questioning me...now wen we r back in singapore he'll still ask me bout him....recently when he calls me n if i happen to b on d other line with my close fren he'll ask me stupid question like who is on d other line n wat r u girls talking about?? r u talking about ur Ex??
his behaviour reali pissed me off... i juz dun know whether i should carry on wit this relationship or not...
