I like this girl but im trying to be careful caz she does go to my gym so I'll probably see her again. When she flaked the first time I lost interest a bit and kinda played hard to get caz I figured she was playing games with me. I've been super slammed with my 2 businesses working 80hr weeks and that's been a part of way It took so long to hit her back up. I'm unsure if I should be honest with her and apologize for why I've been kinda a dick over text or just leave it alone and maybe talk to her when I see her at the gym. Would love to hear yalls thoughts!
