Dating a Gambler

I'm not a gambler, but I am in love with one. She acknowledges she has a problem, but wants to solve it on her own. She sees no need to go to meetings, they upset her and she feels like they don't help. I go to AA and share how 12 steps meetings have helped me to have 15 months of sobriety over alcohol, but it falls on deaf ears. she talks about getting married, but can't stop gambling long enough to save up for a wedding. If anyone has any advice of guidance, let me know.
