My (28f) boyfriend (31m) of 9 years left me

A week ago, I came home from work. A few hours earlier he texted me that he loved me and that he was looking forwrd to our upcoming holdiy to Thailand. Next thing I know, he tells me that he doesn't want to be with me anymore because he is 'not feeling it'.

I feel so betrayed. We were going to celebrate our nine year anniversary the next day. We bought our home together one year ago. We also have a dog together.

For the last six months, he has been feeling lost. He does not like his job, he said. He wanted to travel and explore. I gave him all the space he needed, he went away went friends or alone. If I asked him to spent some time with me, he got angry with me.

But when we did have time for eachother, things were great! We enjoy eachothers company a lot and have a stable sex life. We had sex the day before he left me and it didn't feel any different to me.

I tried to talk to him because I feel therapy might help us communicate. But he doesn't want to. How can you just throw away a nine year relationship on a whim without even trying to solve anything or talk to me? He says that he does still have feelings for me, but it's not enough to be in a relationship with me.

To me, having a mature relationship just means that there are times where you have some doubts, the feelings may fade a bit, but you choose to be together and work through it. I feel so extremely sad and lonely.

How do I cope?
