My boyfriend likes when I cry?

I'm in my first serious relationship and we've been dating for about half a year. He's great, he's one of the nicest people I know and he's really outgoing. He's not afraid to say what he feels. He said I love you first, he says it constantly, and he also says tons of other romantic things. I've always been closed off, I don't like being vulnerable, and it's hard for me to express emotion. I'm very reserved. My boyfriend and I got into a fight (well i was the only one who was mad) and I asked for a break, and after I calmed down and spoke with him I changed my mind. The next day we were in bed discussing the incident and just thinking about it made me cry. I cried in his arms for about 10 minutes (it's not just one thing I've been very stressed) and he held me and wiped my tears. Afferwards he said "thank you for crying". I know that part of it is he likes me being vulnerable but he has on more than one occasion said he likes when I whimper, or fake cry. Is that weird?
