Search Results: breaking up for good

Yesterday, my boyfriend's best friend (let's call him Nugget), a girl that I didn't know, and I went to help a common friend of us move her stuff to a different house. I had only met Nugget once before, very shortly.
But we had a lot of fun together and went for drinks afterwards. We were talking about 8 ball pool, and Nugget mentions that he is in a chat group with some people, that is used to ask 'who wants to go play pool Wednesday at 10?' or something, and then everyone available joins.
That night I was staying with my boyfriend, and I got an invitation to join this chat group. I joined, and told said something like 'Nugget added me to the pool group' to my boyfriend. He was immediately alert and told me that he thinks his ex (who I've never met, but who apparently absolutely doesn't like me) is still in that group. We checked, and she was indeed. I left the group, but now I'm concerned about Nugget adding me in the first place. Is he trying to start a problem between me and the ex and thereby breaking us up? I didn't get the impression that he hated me, but I'm not very good at reading people.

Me and my boyfriend have been together for over 2 years now
We have talked about moving in together
He told me he really wants to move in together

But im skeptical of this for reasons:
- my traditional mother doesn't like me living with a boyfriend before marriage, its not "classy" and she thinks he will take me for granted and won't marry me at the end
- every time my friend or cousin live with their boyfriend, they end up breaking up months later

So im thinking of just moving out to my own place
And i can sleepover at his place sometimes
And he can sleepover at my place sometimes
Instead of moving in together

Is this bad idea or good idea?
