Hello, nimishakhana, and welcome to Psych Central! I think you did the right thing by breaking up with him--and I strongly encourage you not to take him back. He lied to you one time, and he will likely do it again.
I know you are hurting and are depressed about it all, but please remember the good times with him and try to move on.
Are you able to talk to a counselor or a doctor about your depression? Here's the link to our Depression forum:
Depression - Forums at Psych Central. You can get some suggestions for dealing with your depression there. I hope you will feel better soon.
Are you allowed to find another boyfriend? If so, then I encourage you to start looking around for some men to be friends with and then maybe to marry.
That's what I think, anyway. Let's see what someone else says.
