Signs he's messaging someone else on messenger

The specific things you can see and what they mean. Read receipts and online status are tools, but they're easy to misread. Someone can be online without actively using Messenger. They can read your message and put the phone down. What matters more is the pattern over days, not the gaps between individual replies.

If he used to text you back within minutes and now takes hours or half a day, that's a real shift. If he's online status shows him active but he doesn't reply to you for extended periods, that suggests he's choosing to do something else instead. If he replies to you but never asks questions or tries to keep conversation going, he's not investing effort. These patterns tell you about his priority level with you. They don't tell you who else he's talking to, but they do tell you whether he's making you a priority. That's the only signal that actually matters for what you should do next.

Instead of trying to catch him, change how you interact and watch what he does. Send a message and don't send another one. See if he comes back to it. Don't double-text, don't ask where he went, just wait. If he replies and engages, good. If he doesn't, you have your answer.

Stop responding instantly to his messages. If he takes an hour, take an hour. If he takes four hours, take four hours. This isn't about playing games. It's about getting a clear view of whether he actually wants to talk to you or if he just wants easy access to you when he feels like it. Most guys will either step up their effort or fade. Either way you'll know where you stand. The goal is to see his real level of interest without the confusion of his messenger activity status.

If the pattern of slow replies and low effort continues for more than a week, stop messaging him first. Full stop. Don't send the 'hey where did you go' message. Don't ask what you did wrong. Just stop. If he wants to talk to you, Messenger works both ways.

Give him a few days of silence. If he reaches out without you prompting, that's a signal he was just being lazy or distracted. If he doesn't reach out at all, you have your answer about where you stand with him. After a week or more of radio silence from him, don't go back. You're not punishing him. You're just not investing more energy in someone who's already shown you they don't prioritize you. That's the only feedback that actually works.
