This is Kitt and welcome to HealingWell. I have read your thread and I do see some red flags that cause me a bit of concern.
I understand your fears about jumping in with both feet after your divorce but I think that is only the tip of the iceberg here.
Your girlfriend is very young and has little to no experience with men from what I have read and I find this a bit alarming in the real world of today. She has never had a boyfriend and she is a strict Catholic. I am wondering how her family views you as a husband for their daughter with your divorced status. I would guess if they are that strict, they would want a man that would be able to wed their daughter in the Catholic Church etc.
You also seem to be vacillating on what to do and by bringing in her cousin you may have made a tactical error by accident. Hopefully she will understand that you do love her but you have fears.
Have you been to or thought of counseling for yourself to help sort through your fears and issues. I think your fears are well founded but at some point you will have to take the leep of faith and go one way or the other. Yes you may get hurt again but that is what happens to all of us everytime we love someone. We may get hurt then again we may just find the greatest happiness of all...............the love of a wonderful person to spend our life with.

I wish you peace and happiness but most of all I wish you love, Hendrix.
