Need Advice On Reconnecting With An Old College Crush/Friend

I’m heading back to my college town in a couple of weeks, and I’m thinking about reconnecting with an old friend/crush. For context, I’ve graduated, but she’s still a student there. We haven’t spoken in about 1.5 years, and our “friendship” quietly ended.

To sum it up: I told her I liked her, but she ended up dating someone else. I was fine with being friends, but she’d cross boundaries. For example, she brought her boyfriend to my house for a party I invited her to. She also sat front row with him at a Valentine’s Day love themed event I was on stage hosting. The worst was when she sent me a Snap of them in bed together while we were mid-conversation on Snapchat. That’s when I instantly stopped talking to her and didn’t argue or anything. We just haven’t spoke at all since.

At the time, I don’t think she realized how much this hurt me. She came off as immature and maybe just didn’t care about my feelings. Looking back, i think she was just an attention whore and really not used to many guys liking her. She’s not necessarily anyone i feel most guys paid attention to especially in high school and so on. She also played with my brain a lot leaving me to think she had some type of interest but idk. For example, before she started dating him, she did things like dress up as me for a themed Halloween party (using my real clothes, which she borrowed from my closet), randomly text or DM me, and even start long conversations when we’d bump into each other. Again at the time of these interactions she knew I liked her.

Fast forward to now: she and that guy broke up, and recently she’s been interacting with me on social media—following me on Letterboxd, liking my IG posts/ watching stories, and voting and interacting to Snapchat polls. It feels like she might be open to talking again.

Here’s where I need advice: how should I reach out to her? I don’t have any ill intent—I just want to catch up, talk about the past to get some closure, and maybe rebuild a friendship. Again we never had an argument that ended the friendship, I just never responded to the pic she sent of her and her ex and never spoke to her again even after she tried to reach out a couple of times. Should I propose something casual like a walk on the beach, or should I ask her to dinner? Drive around town?

Bonus: If the conversation goes well and the vibe is there, I’d like to shoot my shot and ask if she’d want to spend the night at my hotel. That’s not the main goal, but it’s something I’ve thought about. I’m just not sure how to approach it without making it weird or forcing anything. I ofc would only ask this part in the moment if the vibes are right and not over text when I initially ask to talk.

Edit: I Do NOT Want A Relationship With Her, Just Want To Be On Better Terms And Again Have That Conversation That Was Never Had Since I Quietly Cut Her Off.

Any advice would be appreciated!
