Why would my mothers 68 yr old sister let my ex-husband live with her

he is 51 yrs old and is always looking for a free place to live,and he lives off of old women,im hurt that she would do that to me and my daughter.her husband died in 2005,so now she is more obsessed with him than ever.shes always been very intrested in him .i think they are messing around when no one is around.how do I get over my aunts betrayel

Talk to her about it, and let her know how you feel. If she has any kind of morals, surely she will take your feelings into consideration. I have learned from experience, that this may not be her fault (the obsession, I mean) and could possibly be your ex-husbands fault. I have come to find out that alot of men are great con-artists. And alot of women are naive. I'm sorry I dont have more information or advice to offer you.

Best of luck.
