I think what the coach teaches is proper play here. If she reaches out assume she wants to see you and ask her when she’s free to get together. If she gives you dates and times make a date. Then hangout, have fun and hook up. No relationship talks. If she gives you BS about needing time to herself then tell her your not interested in just being friends and to call you if she changes her mind.
I suspect there is another guy in the background. To be blunt if she really wanted to see you she would find the time.
I’m sorry you have to go through these challenges.
