I'm planning on taking a trip without my boyfriend. It's to get back at him for planning one without me.
How long do you plan to be gone on the trip?
I'm going to a city more than a day away from home and he's going to a city a few hours away.
I think it's fine for you and your boyfriend to take separate trips. Couples don't need to spend all their time together, and it might be healthy to be away from each other for a little while.
Yeah, but I'm worried he's going to cheat on me while he's gone.
If your boyfriend hasn't given you a reason to distrust him, then you should have faith that he'll be loyal to you. We can't be with our partners all the time, and it's important that we can trust them when they're not with us, otherwise the relationship will be stressful and tense.
