How do I (32M) know if this woman (35F) is actually into me vs. just feeling obligated to go out.

I'm a total white belt with dating so I know this is probably a dumb question. I actually gave up on it recently because I never did it much coming up and I'm rapidly figuring out you don't learn these skills later in life.

Anyhow, met this woman at a nonprofit event and we talked for a while, agreed to continue it some other time. Initially she didn’t respond to my texts so after a couple tries I figured she wasn't into it. That's fine, it happens. Then three weeks later outta nowhere she messages me wanting to grab a bite. Seemed weird but why not. So we went out and had fun, told her it'd be cool to do it again sometime and she agreed, then silence for another couple weeks. Again, ain't tripping over it.

Then she reappears again asking to hang the next week, and suddenly she’s responding to texts the same day. There’s so much inconsistency here and it seems like she ain't genuinely interested and is doing this outta feeling obligated or wanting to be polite or something. Like she wasn’t interested but felt bad for going awol and feels like she needs to placate me every so often. If imma do this whole dating thing I’d rather be with someone who wants to be with me, not someone doing it outta pity.

How are you supposed to tell what's real and what ain't?

TL;DR this woman is sending mixed signals and I can’t tell if she actually likes me or not.
