Boyfriend does this after sex. Confused?

[oh so Gwhey<3]

I have been with my boyfriend for 6 months and we have been having sex for 4 months. Everytime that we have sex, once he has orgasmed he immediately will go on facebook. He doesnt cuddle or hug me, just grabs his phone and goes on facebook. I want to stay in bed and he leaves me and goes to another room to the computer/facebook.when he goes on facebook he just scrolls through the newsfeed

when i asked him why he said that after he orgasms he needs space. he said he doesnt know why maybe that he needs to recharge because he feels his energy is drained.

he has always done this from the very first time we had sex and i lost my virginity to him. and i felt very upset he didnt attend to me but went on facebook and got up and left straight after. im confused if he loves me or not by his actions. thanks
