I'm so sorry you had to go through this, but you sound like you really get it now. It rook me 2 divorces to learn what you already know. There was an author on Montel (She was on the show The Bachelor) who was saying that it's better to be alone than in an unhappy relationsip. I totally agree with her.
No woman should allow the pressures of their families and society to push them into a marriage they're not sure about. Just be happy.

My heart goes out to you...I'm am going through this with my 24 yr old daughter right now. Her boyfriend of 6 yrs told her (4 weeks ago) that he wanted to break up with her to see if he really wanted to be married. 2 weeks later he met a girl at a bar and took her home. To say the least my daughter was absolutely devastated! In the beginning she cried all the time and, I cried right along with her....not because he couldn't make up his mind in 6 yrs, because my little girl was hurting. After she found out about this other person she got angry. Her emotions are on a rollercoaster. She has alot of support from her friends (which she has many) and especially her family. After giving their relationship alot of thought she has realized that he really isn't what she wanted. He is very selfish and only thinks of himself (theirs alot to this but, won't get into it). He has NEVER put her first and, is now starting to say very hateful, hurtful things to her. She is getting her own apartment and starting a new life...I thank GOD that this happened now and not after they were married...imagine how hard that would have been.
I really believe that if it's meant to be it will...life teaches us hard lesson's that can really stink but, in the long run you may be better without him. I know you are heartbroken right now and, I KNOW it's going to be hard but you will get through this ..

Wow, she's better off without him!

Last Valentines my fiance just ended it out of the blue for no reason... so I know exactly how she must be feeling right now. At least she's putting herself first and getting out there again, good for her!
