Me n my girlfrnd wr committed for two years.. like all relationships even we had petty fights.. but i loved her no matter wat.. but i liked a girl before she came into ma life.. n before me n my girlfrnd got committed i told her abt ma past.. she says ma past started haunting her n we fought daily over that matter.. if i said past is past .. nothng good will happen worryin abt it.. she still neva used to listen to me n fight over that matter.. she says she couldnt forget ma past.. now we hav broke up n she easily forgot me.. but she could not forget my past.. do yu think i should move on.. i moved to another country for my higher studies.. n here two girls directly asked me if we could hav a one night stand.. should i move on.. i dont want to hav meaningless relationship.. wat i had wit ma gf was good.. cause in two years we kissed n got intimate wit each other.. but never had actual ..
