Hey guys I'm a 20 year old junior in college new to Seddit looking to turn my game around breaking up with a gf of three or so months.

I don't want to ramble on too much so I will get right into an interaction I had earlier today with an acquaintance I know from one of my classes last semester. She's the same age as I am (actually she just turned 21 today) and seeing as it was her birthday I sent her a text. It went as follows:

Me: "Hey happy birthday, hope you have a good one"

Her: "Thank you so much! Who is this I got a new phone so I don't have your number saved angry emoji"

(I kinda figured this was bs)

Me: "It's Brillyx you weinee"

(At this point she didn't respond for a long time and I was second guessing my reply, this is one of the things I want to work on because I ended up double-texting her)

Me: "But for real I hope you have a great day and a safe night"

Her: "Oh okay! And I'll try my best hahahaha hope you're doing good"

Me: "Yeah I've been doing pretty good just getting through classes this semester, speaking of which you should just skip class tomorrow and party all night smirk emoji"

Her: "Hahaha I'm going out tonight but I'm going to try and make it to class tomorrow haha"

And that's where the conversation has ended so far. I'm thinking of sending a message back calling her lame or something for trying to make class, but if she is out tonight I don't want to be "that guy" that is pegging her phone while she's trying to party. Maybe I should send a flirty reply ending the conversation?

In addition, I am a very soft-spoken individual. I wouldn't say I'm a beta by any means I've been with girls here and there over the course of a two years, however, it's no where near where I want to be and I've been self-improving myself since the summer time such as visiting a therapist, taking Zoloft for depression/anxiety, and trying to get myself out to meet new people.

I've rarely ever done game, though. I've been told I'm very attractive but I lack the wit to really use it for anything. I almost never approach and it's something I really want to change and start doing, as my old gf was such an emotional wreck and a leech and I know I can do so much better for myself. How was my texting this time around? How do I know what is flirty and teasing but not arrogant or being a dick? I guess I should check out some shit tests but I wanted some real-time opinions of my scenario at hand. Thank you.
