DP and I have been together for 3 years.
We have both been married before and both have DC.
He left his ex wife as they had a very tempestuous relationship and it was toxic to both of them, they had been together for 6 years in all.
We met a few months later, and now live together and I'm expecting.
His ex wife has had a few relationships but now seems to have someone serious.
DP has been acting strangely, really off with me and has fallen out with his ex because he's asked to meet the man who'll be spending time with his DC and she's said no....
I'm not sure if he's being off because he's stressed out with the situation or because he's dealing with her moving in and it hurts....
