Should I be mad about this!!

I known this guy since 2012 while in college but never talked to him.  We was crushing on each other for the longest but I never gave him the time of day. Well recently I gave him my number, & we started texting, I went to visit him a weekend. So we kind of got close. Well he told me that he had sex with an old ex. And I feel completely hurt because we both express our feelings towards each other and even though we're not together we established that we wanted to focus on each other. Yes I had sex with him which makes me even more mad and the fact that he's coming home this weekend and staying at my place is like seriously! Should I have Kirk out on him for him being honest and telling me this even though we're not together.
