How can I make him love me more?

If you're spending time with him and making him happy, but he still doesn't 'love you as much', then there is nothing really you can do.

You can't MAKE someone love you.

you just can't.

And if they say yo ucan, then it would be fake love and it will end badly. I'd just try some new things, go out to fun little places like Mini-Putting or something you would do on a first fun date. That's always a way to go.

No movies, that's tacky.
I hope things work out for you two. I know you have made a lot of sacrifices for this, but don't feel bad about them. sometimes Sacrifices need to be made, and sometimes by going through a relationship that a lot are made you can learn a lot.

Either way, I hope things work out.

Just remember, you can't make him love you
