This guy and I were dating casually but due to personal reasons I had to move away so we broke it off since I thought I’d be gone for quite awhile. We weren’t ever a couple but we were consistently seeing each other and I had feelings for him. Now I’m moving back for reasons, I was only gone for about a month. I told him this and we both said we would go out again once I move back and he seemed excited. He knows I want something serious and have feelings for him, so I assume he thinks there’s potential for it to become serious? But I told him a week ago I’d be returning in a month and my friend who lives back at home said she saw him recently active on a dating app. If he’s still frequently going on dating apps while he’s planning to see me in a month... is this a bad sign he isn’t that interested or serious about seeing me again?
