It does not sound like she knows what she wants out of a relationship or she does not want serious relationships and only flings.
It may be a good idea to find out where she stands. Unless she is absolutely committed to a relationship and to make changes in her behavior, she will continue to act like she had done i past situations. You would want to ask yourself what do you expect from her and if why you're interested in her.
She has changed her behaviour and ways and is def commited to us but i think u misunderstood those were the course of events in the begging of the realtionship about 5 months ago . But i have big worries looking at her behaviour in the begging and now that she has a successfull buisness man she knows its a good thing . We she get the 5 year itch and go back to her old ways and leave me being hurt like she did to her ex-husband . Should i get it now
If something is bothering you, there is a reason for it and you would have to work with it. Maybe at the back of your back you;re wondering still about her commitment.
If she is willing to go to couple's counseling, you could see what she's got to say and work the issue together versus you by yourself.
