His great grandmother is trying to wreck our relationship!

So let me begin by stating that I've been dating my boyfriend for almost 10 months now, and he has repeatedly told me that he doesn't want to break up and actually wants to start a family with me. He's 33 years old and I'm 32. The only issue is that he is still living with his great grandmother who is 92 years old and raised him (so she's been practically his mother). She does everything for him like cooking and picking up after him. She has spoiled him rotten to be frank and treats him as if he were still a teenager. I know she seems very old, but she's in a perfect state of health and her memory is still intact. In other words, she's going to be around for a very long time. The problem is that she has started to interfere very much in our relationship, and I don't know how to handle the situation anymore.




My boyfriend has told me that his great grandma has ruined almost all of his previous relationships including one where he had a live-in girlfriend for 2 years. This girl put up with the old woman during that entire time and they fought everyday. From my personal experience my best guess is that his great grandma was the one who started all the fights because she is very confrontational and will insult you right to your face. She has done this with me on several occasions and all I do is ignore her and walk away. Because of her advanced age I don't talk back to her. The tip of the iceberg was when she recently said out loud with both my boyfriend and I in the room that one day he's (i.e. my boyfriend) going to find a lucky girl to settle down with. That was the ultimate insult for me. At least my boyfriend stood up for me then, but he's never stern with her. I know he respects her, but I feel that unless he puts his foot down and tells her directly to butt out of his personal life, then the great grandma will continue to feel as if she's still queen of the house. Mind you, that house belongs to my boyfriend, not her.

It's so bad that it's getting to a point where my boyfriend is asking me to stop coming over to his house because of his great grandma. My fear is that we will start seeing each other less, and that will ultimately lead to the end of our relationship. I haven't left him because I think he's the one. I can see a future with him. But at the moment because he has the old woman to contend with, our relationship is at a stand still. We can't even live together because of his great grandma. No one else in the family wants to take her in and she doesn't want to move out so my boyfriend is stuck with her for a while. He's already depressed about the situation because he thinks I'm going to ultimately leave him just like his other girlfriends did because of his great grandma.

What do I do in this situation? I don't want him to kick her out, but it would be nice if her attitude could change. She's possessive and jealous and wants to be the only woman in my boyfriend's life. It's sickening how rude she can be. I'm at my breaking point and don't want to put up with this for years (or however long she will be alive for, candidly speaking). What shall I do?
