My ex wants me back

My ex dumped me about 3 weeks ago after ten months of dating. I didn’t see it coming at all. I thought we were perfectly fine. But he’s in ait graduating in about a month and he claimed it became to stressful to have a relationship and be in ait. He thought I’d be better if he was alone. But a few days ago he started messaging me saying he’s lonely, has realized how much I cared about him and that he wants to try to fix himself so maybe we can get back together when he graduates ait and gets stationed. Hes even talked about us living together when he does get stationed. And sure this is all fine. I do still have feelings for him and missed him a lot. But he wants to keep that fact that we’re talking a secret. He even had Snapchat (we always talk there because he can play his games/videos and talk to me without changing screens or whatever) delete that conversation where he said all of these things. He claimed he didn’t want me screenshotting and making people think he’s an asshole. Cause I kinda did that when he broke up with me but he deserved it. But him wanting to keep it a secret kinda unnerves me. But I see and talk to his friends from here daily and my family now hates him so maybe it’s reasonable? I don’t know. Is it even reasonable to try to get back together and possibly live either near or with each other after he gets stationed?
