What do I do? I love her? She says she has never made love like we do! She needs to be alone often! We see each other once a week! What do I do

Good sex does not equal a good relationship,or in fact any relationship bar a sexual relationship exists.

Possibly this lady is enjoying your company but not looking for serious involvement,the fact that you say she is still in love with her ex husband should be a red flag to you.

She likes to be alone,or with other people,it sounds like she is single,and trying to get her life together,just because you love her,does not mean she will love you back.

How long has she been divorced? How old are you two, and how long have you been dating??

More info please.

Going by the title of your thread I must inform you that when someone isn't over their ex you can't have a relationship, and shouldn't be considering having one with them.

While they are stuck over someone else, they are unable to give themselve to you 100% and the relationship will be doomed.

Until the person is completely over their ex, there's nothing you can do. You don't want to be the "rebound".

More info, but if she isn't over her ex husband, you aren't going to last together
