Too fast

I’ve been with my boyfriend for about 2 years. Moved in right away. He is 29 I’m 23 he started to talk to me about how he feels like we are moving too fast now. That he craves to have his own space and encourages me to do the same. The idea hurts because i really didn’t see this coming. He had issues with staying hard and tells me he doesn’t have sex drive at all. I understand and all but I could see him being in a funk right now. I don’t know how to fell I don’t question his love for me at all but I just need some advice please 😔
