So I've been seeing this girl for 3 weeks now and all was perfect, the conversations were flowing, the kissing was good and she seemed genuinely interested in me. But then the other day like another few times she sent me a screen or a convo she had with an insistent guy who was asking her out even though she always invented an excuse. The other days I would joke about it but this time I dmed him to stop it because she's seeing another guy.Since then, shit started escalating, she leaves me on seen, replies with single words , she doesn't even text me if I don't. I asked her what's wrong, she told me that we should talk. Now, I haven't met her yet but it's obvious that she doesn't want to see me anymore. So guys for f sake don't make my same mistake, don't do any stupid shit, keep your cool, don't act like you care too much, if she acts weird or does shit like this ignore it or stop texting her, she'll come back to you. Don't give her the chance to take you for granted, even if it's 2 months you're seeing her don't let her treat you like shit, if her attitude, her behaviour is bothering you or she does something that you don't like make her feel like she is losing you, only that will make her chase you. If you say always yes and agree with her even if your opinion is different she's gonna get away. Show you got personality, don't put her on a pedestal, show us who is in control.

Edit: she still didn't dmed me and she said she wants to talk. She has got my ukulele at her house and should give it back to me. Should I ask her to tell me through chat and then go and take my ukulele or just wait till she sends me a message?
