There are two ways to look at this:
A)
You have a great guy who is marrying you despite you being divorced. He loves you apparently and is willing to forget the past and move on towards a bigger and better future. If you are physically attracted to him in the slightest, you could marry him and work on your relationship. Try to get closer to him, do things with him, talk to him, teach him things, etc. This will require patience and can be highly rewarding also if the other person is cooperative and willing.
B)
You marry him knowing you dont even like him...and that dislike grows into resentment which later turns into hatred. Marrying someone because you pity them is wrong, doesnt matter if you were divorced once or five times. Why? Because its not YOU whose life you're ruining (remember, he loves you so he will do his best to keep you happy)...its HIS. Who would want a partner to marry them because they felt sorry for them? I know I would probably be more upset knowing I spent even a minute with such a person.
The question is, are you willing to put in the work/effort it takes to have the first scenario? IF you are, then marry him. IF NOT, then dont.
THANX PS SQUARED,,,THATZ A VALUABLE ADVICE :)
