I don’t think I can answer that for you unfortunately, it’s something for you to investigate with yourself, and at some point possibly with a potential partner too. There are also aro/ace communities around (sadly the ones on the fediverse seem pretty dead) where you can talk your feelings through with people who are going through a similar experience.

Either way, having friendship and intimacy to offer is a lot, and enough, don’t let any social constructs make you feel otherwise.

At the end of the day “relationship” is a pretty wide concept and it includes friendships as well as sexual and other partnerships, and no two are alike (despite what we’ve generally been socialised to believe - either completely platonic or the hetero-romantic boy meets girl, they date, fall in love, move in together, get married, have kids). What’s important is that you find relationships that work for you (and the other person/people involved of course), and the only way to make sure of that is to communicate as openly and honestly as you can with yourself and each other (so for example what you define as a “friendship with intimacy” might qualify as a romantic relationship to some but not to others).

Also - aromanticism, like other orientations, is a spectrum, so you might be greyromantic or demiromantic, which probably only confuses things more (I know it did for me, and so I’ve never really taken the time to figure out exactly where I fit on the aro/ace spectrums beyond knowing I’m on them), but just know that there are options for you to “try on” and see which fits most comfortably (if any!).
