Is expecting a text once an hour bad?

Sorry, but I think that's unreasonable. Texting someone every hour takes a lot of effort and will likely interrupt anything your partner is doing (hanging out with friends takes longer than an hour, doing work takes longer than an hour, etc.). I think it'd be more reasonable to expect a text once or twice a day, if you're willing to compromise. A text at least every hour is going to be 16+ texts a day depending on how much your partner sleeps. I understand that you might be anxious or insecure about your relationship but you might want to work on that instead of making your partner text you every hour.

I'm of the belief that people are allowed to want whatever they want in a relationship (excluding abuse and things like that, of course), but asking your partner to text you at least once an hour is kind of a lot. You can of course request that your partner do that, but don't be surprised if there's some pushback. Just like how you're allowed to want what you want, your partner is allowed to set their own boundaries and make their own decisions about if you two are compatible. There are people out there who would be happy to text their partner 100 times a day, and if texting that frequently is important to you then you'll just have to keep looking for someone who is willing to do that for you.

I think it's unreasonable, yes. Your SO might not have enough time to talk 24 hours a day. But you definitely should talk to them about it and see what they say!
