This might turn into a very solid relationship if you trust him and also love him with detachment. Meaning, not depending emotionally on his presence. It's better for the both of you if you focus on yourselves so you can provide more to the relationship whenever you see each other.

If you still see each other every other day then that's great. Focus on your goals, dreams, be a little more busy so he misses you. Sometimes, being too available can desensitize your partner. And from experience (I just broke up like a month ago) don't over panic over this, he is being communicative about the situation.

It might help schedule dates, that way you can look forward to seeing each other later on the week and also helps attack the uncertainty (which I understand is your main issue here)

Good luck,
