Uncertainty around romantic or platonic feelings

Okay - so I’ve been seeing this guy. We have a lot in common he’s super sweet, treats me fantastic. Seems to adore me. Puts a lot of effort into maintaining a relationship, even now that we’re long distance. Things feel very platonic though. We had sex one time the whole 6 months we’ve been getting to know one another. It felt .. awkward to say the least.

I’m a little worried about my lack of certainty about how I feel about him. Things truthfully feel more platonic than romantic to me and I feel like I’m usually the kind of person where my intentions and desires are pretty dang clear to me. He asked if we can visit soon and here where I stand. Any advice

1. Maybe after some space from each other seeing him /being around him in a context outside of where met (summer travel job) will give me definite answers to what I’m wanting from this relationship

Or

2. Take my uncertainty as a red flag that either this isn’t it or I’m not ready for a relationship (maybe both) and break things off now instead of traveling to visit each other.

I do care for him dearly as a friend and I just don’t wanna string him along out of uncertainty. I fear loosing him though out of “maybe I’m just not ready yet” either though

Ugh 🤦🏻‍♀️

What are your thoughts/advice please ?
