Communication advice?

My boyfriend has been a bit closed off lately.

He came home just over two weeks ago and said that we should break up. This was after his mother had stayed at my family home for the weekend. She said to him that our family values don’t align and that we don’t have a future - even though there had never been an issue before.

We talked it through the day after on the phone and a few days later in person and decided that we did want to be together but that there were some things that we needed to work on. We had a lovely few days around Valentine’s Day and everything seemed like it was back on track.

On Thursday he had a hospital appointment, I went with him, and he was given the all clear after a cancer scare and fairly major surgery a few months ago. I have been to every appointment with him while his family have only been there for the biopsy results and the surgery.

I have been at my family’s house since Friday evening (I came up after celebrating and having Valentine’s lunch with my boyfriend on Friday). I told my boyfriend that I would stay up for a few days as my sister turned 30 yesterday and I wanted to also visit my cousin’s new baby. Everything was fine.

On Monday when I called he was in a bit of a mood and just said that we shouldn’t live together anymore but that he didn’t want to be stuck on the phone and talk about it then. I was left feeling very confused. We spoke yesterday and he said that we should look for separate places to live but that we’re still together.

I am going down to talk to him today and to stay in the apartment with him for a few days. I was offered a new job yesterday (which had been causing me stress for a while) and so he knows that things will be changing and that we’ll have more space because of that.

We’ve been together for almost two years - although it seems like much longer as we’ve lasted through three major moves (we both moved from New York, and then he moved to London for a few months for work before moving to our home country); he was the first year person that i opened up to about being raped; we’ve been together throughout his illness; and we’ve moved in together.

I don’t know what’s happening but I do know that I love him more than anyone and that he does love me. I just think that we need some help with opening up the lines of communication a bit more and getting to the root of whatever our issues are. I do want to try and make this work as I know I would always regret it if I walked away.

Sorry that this is so long but any advice would be greatly appreciated!
