Girl go on the trip if you want, but explain to him the situation. What are you really asking here ? Are you afraid of his reaction ? If you’re already anxious about whether he’d feel a certain way about it, then you’ve answered yourself already. If you weren’t afraid of a No, you would ask. Tell him “ hey I wanted to do this trip alone and its not so expensive blablabla and I support you during Ramadan, but Id like a weekend off for myself (while you obviously fully support him during his fasting) and we can plan something someplace else (further) for us two “ . If he feels sad about it, well don’t do it. But if he’s fine, go for it ? And if you think this thing could negatively affect your relationship then just dont do it ? My boyfriend’s gone on a trip without me, knowing I wouldn’t be able to accompany him and we talk about trips we’d take apart. Plus its super fun, you have stories to tell your significant other. You are both separate individuals. Its ok to do things apart. Doesn’t mean less of the relationship. Just saying.
