Ok everyone, let me share this issue with you here, where i really hope to get some really good, sound advices and suggestions.
I met a guy through one of our common friends around 3 months before,as he was looking for a girl to get married. So, initially we started chatting with each other online, then through phone calls and text messages, and then we decided to meet each other in real, and we met after 2 weeks, in a shopping mall for 15-20 mins. So it all went well,and we kept on talking on phone and online, and after a few days, he told me he wanted to take it further,and he wanted me to talk to my parents and get him a date as of when his parents could visit them with the proposal.But i couldn’t talk to my parents as i was scared,and moreover i wasn’t sure of him,as i felt his interest getting declined after a month we knew each other.He wouldn’t call me like before,and if i did,sometimes he would talk properly,or sometimes he would give me reasons like,he is busy in work,busy eating,etc.If i text him,he wouldn’t reply back,saying he hates texting,and initially he did just to get to know each other.He stopped coming online,and even if he would be online,he would chat for a maximum of 10 mins,and would then give reasons and go offline. So, there was kind of no contact between us,and i was wondering why he was acting in such a way.It was like I had the lowest priority in his life.I questioned him regarding this,and it ended up in a big quarrel.He tried reasoning it.After that, I left him alone for a couple of days,and then i emailed him that,if he wanted to end everything.He replied back, saying, when i wasn’t there,he is now used to living without me,and that,he had peace of mind as there was no nagging,taunting,questioning,etc, and that he knows i was all okay without him as he saw me being on facebook, and he said he wanted to end everything.Initially i resisted,but when i accepted to break up with him,he kind of started saying he was kind of gone mad at how i sent him so many text messages and emails,and that he loves me.
Okay, so now, what should i do? Whether i hold on to him or let him go, it is hurting for me both the ways. If i hold on to him,his behaviour will keep on haunting me and giving me heartache, but whenever i think of letting him go, it hurts me even more, and I end up finding one reason or the other,and keep going back to him. What should i do? 
Please help.
