I share the same story, word by word...jst a few nos here & there. Its been 1.5 yrs pursuing this relationship without any commitment from him. Same as you, have tried my best to break away...but However he is relentless and comes back with more force with a promise that he would make this relationship a success one day....but hasnt done a bit to prove or atleast start walking/working. Whenever i give up or escalate, he jst assures in words but no action so far.
Its very frustrating now...as its strange to be in love with a person who is not there to emotionally support you when you are falling and does not realize wat the other person is going through/forgoing in waiting for him without any certain time frame/comitment.
Like you i am too seeking for the right direction/advise.Actually i want to get away from this mess as this love is not helping me to grow spiritually & positively.
