<human>: Not sure where else to turn for advice

But my me and my long term girlfriend of ~3 years broke up at the end of last year. I was in a really bad place and pretty much just threw it all away and didn't give a shit. I was over her and didn't give a shit about anything in my life really.

Since she has gotten a boyfriend and idk if they're still together or not, I'm not one to look further in to it. I've "heard" a couple months ago she missed me, but kind of ignored it, as I still wasn't in the best place. 

But recently I texted her and apologized for me pretty much just ignoring her for the last part of our relationship, and how I didn't want her to think she did something wrong, and didn't get much of a response. 

Then yesterday I get a huge text from her apologizing for how she thinks she's stepping into my social life because I don't get invited to go to places because we still have the same general group of friends, and she gets picked over me(they think we can't be around together) and how she doesn't want it to be like that and how she genuinely cares for me as a person, and is happy for me that I'm not in a shitty place in my life anymore. 

Feelings I thought were gone long ago are being brought back up, and I miss her terribly. I'm probably out of place with this feeling, and I don't think I should tell her I have these feelings but I really want to, and I'm thinking about her constantly. Please help me, I don't know what to do and I don't want to step on any toes.

Provide a brief overview of the text.
