She turned on her read receipts?

Okay - I’m 29M, and was in an LTR for 3.5 so I’m a little out of the game & what/if certain things means anything.

I have my read receipts on.

I met a 25F back in early April & have been slow playing it since I see her once per week. I usually text her once throughout the week as well.

Last week I texted her and her initial response was dry, I was busy working on my vehicle so I read it out of habit & thought I’ll deal with it later. She must’ve saw I read it and double texted me. We ended up having a pretty solid convo with some clear flirting.

Today I texted her for a valid reason and noticed she had turned her read receipts on.

It may have 0 to do with me, but I found it sorta odd. I guess I turned mine on at one point & everyone who texts me probably had the same reaction.

Is there a reason a girl would do this? Or am I reading too much into this? Just seems strange considering I started texting her last week & mine are on.

Thanks!
