I don't see anything definitive in the description of this whole thread that I can draw any conclusions from myself. i'm not convinced your partner is bad enough to break it off without a lot of thought nor can I say without a doubt he's the one for you but I can say that it doesn't seem to me that you'd be here if you were in a relationship where it was so bad you need to get out, after 5 yrs.

his social issues, it seems to me are not necessarily deal breaking. I think if you were so socially active that it was impeding on your ability to stay in that environment you'd have likely said so but it sounds more like you're apologetic and worried about people's impressions of his behavior on his sake to me.

Lilving with someone that happens to take over in conversations and talk over you is not entirely an uncommon nor deal breaking thing imo either. everyone has flaws and whether or not its something you can live with going forward, is something only you can decide, no one here can judge from your short descriptions whether or not your conversations are so bad that he needs to be sent away. take what you can from the conversations here but I am of the opinion that it's good to take in advice but weigh the source. this source online cannot have a direct line nor view of your relationship so it can't be completely objective, which is why I personally keep the ball in your court and try to help with perception and analysis on your part.

The only take away I hope you get from this thread is, think, and do not act on emotional highs or low but practical rational thinking and analysis. long term what's going to make most sense is acting on the side of practical and logical thought more so than emotions. Note I did not say WITHOUT emotion but more so on the other side.
