for me how about u give him a bit of time to adjust and adapt his life back to u. the same goes with u.
to work out this relationship back, u have to give some time fo both of you guys. try to have a good talk.about how you n him going to make this relation as possible.
make him understand if he want relationship with u. then he must have only u. try to ask him why he want u back. try to think the logical of him getting back to u.ask him heart to heart.what he want from u n this relationship. then u also need to tell him what u expect from this relationship.
like i said. give some time to coop. maybe he have his own reason for not going to the game. just dont think too much. just ask him nicely.plus. u still can do other things together right.
