Can he loose feelings for me after 2 months?

So there is a guy who likes me and we have known each other for 2 or 3 months. Anyway when the next school year begins I want it to be the same as this one.I don't want him to be just another person to hang out with cause he might loose interest in me by not seeing me in 2 months. We might talk once in a while and maybe see eachother once. He won't be seeing a lot of people though and there is only 1 or 2 people I am concerned of taking my place. I just want to know will his big crush on me loosen?He said nothing will happen between us and by a couple weeks he will be desperate to see me.
