Does my boyfriend still want me? Help

Ok so here's the deal, I have been with this great, loving man for over 2 years now. He is so great to me and I'm happy to say I love him very much. I just recently got over my period and the whole time I was on it he was constantly horny saying he can't wait to have sex once my period eneded, today it was officially over. We were just about to have sex until I had to try to get him hard MULTIPLE times until he just gave up and said "I'm not even horny this isn't going to work" I was very very upset and blamed myself for not making him horny enough. After that I was kinda mad at him. He then told me that all day he has been thinking that we should pick a day to spend time to ourselves bc he thinks we spend too much time together. He also said he doesn't wanna take me for granted and he wants to be able to miss me. 
Is this all my fault? Is he falling out of love with me? Please help I can't bare to picture life without him...
