Hi,thanks for sharing your condition at hcm.

What I would suggest is give time to yourself. Make yourself better than yesterday. Get involved in some cocorricular activities or something other than studies or relationship. Go on a small trip if you can get leave.meet new people on the earth. you can get new ideas to enjoy life..

Prince William and cate midolton is the famous example. prince broke up with her at a times during their 8 years of dating.but what did care do ?! She went on dance floor and enjoyed life..she concentrated more on career at that time..she believed that only Prince is not her way to happiness. Ultimately what happened is prince came back to her !!!

A famous writer from India, chetan bhagat has told " Is making bf/gf is the only thing you have to do in life !!?? Waiting for him/her when he/she is not interested is your life all about?!! YOUR LIFE IS PRECIOUS TOO.make it best ..make yourself better than before and develop new connections around the people on the earth..

And about cheating and that prostitute thing.. just think on it..that prostitute will leave him if she is getting someone more rich than him !! And good that he cheated you at this stage and not after marriage.. you could better save yourself and your kids from falling in divine relationship with a cheater like him at right time..so whatever god does is for good !!
Just don't underestimate yourself!! Show him that you deserve better than him .take the hurt he did to you in a positive way to improve yourself.. and personally I believe being single is good thing in two ways
One that we can give more time to ourselves our family and other people than only one person who is your gf/bf and second you have chance to meet someone new on the eartb beyond the level to choose him/her as your significant other part..

Wish you happy living.. good luck .
