Re: She was into me, but now she's evasive by phone
A few things. If things went well the first night, you should have definitely texted her after you left, something funny. And then kept the texting going - keeping it flirty and fun. You waited too long in my opinion. Then, when you did contact her, it was on V-day! That's definitely a no no! It's just oozes needy. And then the texting about what she's up to, etc... also screamed needy to me. Having said all this, I don't think all is lost, but you need to make sure you stop with the needy stuff. I suggest text gaming her. Keep it cool, cocky, funny, flirty... then invite her out again to something cool. Some event, so new coffee place, etc. etc... and get that one on one time again. You were obvisouly doing something right the first night. Once you get her out, and it goes well, you need to text her flirty stuff pretty quickly after, etc. and escalate.
The world is your matrix. You control the strings.
