Hm what to think?

I knew this guy last year and we talked a bit but for some reason we werent getting each other's texts so we mutually stopped talking fast forward to now .. all of a sudden he's liking all my pictures and such... I go on his fb profile and notice he's not in a realitonship anymore [ they were only together a couple months] then all of a sudden I get a message from him and we talk a bit and he says he still has my number and texts me he says he will call me so we can actually make plans... does this seem like he wants me to be his rebound cause I ain't got time for that p.s he hasn't called and it's been a couple hrs...
