Search Results: hanging up on a girlfriend

I guess this is a follow up to my last question. I was hanging out with my ex girlfriend today at work (we work together) and she was chill the whole time still. Since I dumped her she'd always occasionally try and talk to me or say something to me. I initially ignored her because of her shitty friends mostly, and because I wasn't sure if I wanted her back, but I now I do. She's apologized like 3 times now, and she said she understands what I meant when I said I was legit busy and not cheating like she thought 😑. The only issue I have now is figuring out how I should go about the whole thing.
Like should I text her first? I told her she could text me if she wanted to after the whole valentines day thing, but she never did (I think because of her friends) but if she wasn't at least a little interested she wouldn't be talking to me and inviting me places. It would be out of character for me to text first, and I don't know what to say

My girlfriend has a couple of male friends that she’s known since high school that like to come over to her apartment to hang out sometimes. Her two male friends don’t know each other. They come over separately. Mostly they hang out with her in the privacy of her apartment usually after 7:00pm.
I don’t know if I’m being insecure but I think hanging out with a guy friend one on one in her apartment isn’t something they should be doing. I think they’re stepping over a boundary. What do you guys think? Would you put up with that. I think it’s weird, and yes I do trust her.
