Should I get over him or fight for my love

hi, I am 25 my colleague aged 28 pursued me to fall in love and it went thru for over a yr and i was so true to him and i made my mom meet him but then he starting changing as he did not have the guts to convince his dad.He went away again he came back begging..He was on and off more than 5 times.He said he cannot live without me and he cannot let me become someone elses wife and he will do everythin to marry then he changed again. Everytime he came back i forgave and accepted him but he broke my heart everytime he was always confused not able to make a single stand and finally he left me saying sorry for all that he did to me ..His claim was he does nt want to hurt his dad at his old age.I tried so hard cried and begged him to save our love but hewas so after his family and as we were from different castes he was nt ready to take the risk. he gave me all hopes for 1 yr n he cheated me fr bein so true to him, I see him everyday at work and i cldnt forget him and i cry everydy. i cannot imagine another person in my life. also his mother had psychological depression and committed suicide . Both his elder sisters who are married also had serious depression issue and are now better after meeting a good psychiat and under treatment. SHould i fight to get in to such a family,, or is it safe to stay away as he himself is not sure and thr are so many people in the family affected by depression. What could be the potential risks i face if i convince him and get in to such a family.. Will my baby be affected as it is in their genes... He hurted me a lot though i was so true to him and i wanted to be a one man woman he shatered al y dreams and i feel hopless. everytime i see him in office i feel like begging him to come back. i cant imagine another guy as my husband,,pls help

u need to have a straight talk with him if u r still serious about him, after going thru your contents very honestly if u ask me its not worth to give a try again because anyway he is not serious about u and keeps changing his mind, i mean even if he is serious he isnot ready to fight for it, not ready to go thru the trouble of confronting his parents, hence whats the use to stick around with such a man. i am not giving much importance to the depression part in his family, that has nothing to do with ur issue, but when this guy is not ready to support u and face his father is on and off hence better to have one last serious talk with him giving him a deadline to approach his father regarding u and still if he doesnt proceed then u got to quit, ya otherway round is if u have the guts go and approach his dad directly or thru ur family and inform his dad about ur relationship if hes not talking to his father about it. though actually hes got to inform his father and not u but if hes not doing u do it if u r very serious about him. i mean dont hang on with this on and off situation and take a final call. try to understand if this guy is not ready to fight for u then what will he do in future if a situation demands him to take strong action to support u, that time also if behaves this way then where do u stand , i hope u got me.. my webplace http://www.songofgod.blogspot.in
