My last (and first) relationship / oneitis ended on a horrible note.

I am trying to pickup and apply concepts from TRP, specifically plate theory and abundance mentality.

There is this one girl in my class, maybe 20-21 years old. We have been talking for a week now, and flirting on snap. The problem is she has gotten out of a 4 year relationship, and I presume her BF was the one that dumped her. I believe it has been months and she still has not cleared their couple photos from Instagram.

My main concern is that I will see this girl in every one of my classes. How do I approach this without seeming needy?

For example, in our program we will be together until we graduate (~ 2 years). I understand abundance mentality is key in TRP, but is the fact that we see each other everyday advantageous for me or not? Will it not make me look needy if I am constantly seen sitting next to her, talking to her, or doing assignments with her?

This is confusing to me. There is one couple in my program that have been together since high school. They are in the same classes as me, and they always sit together, do assignments together, etc. They're relationship seems just fine,

She has gotten out of the 4 year relationship (must have been her first). I don't know, maybe alpha widow is the correct term her, but how do I carefully approach this in my favor and what should I watch out for?

Finally, what do I do if the discussion of "ex's" comes up? She already knows a little about my breakup.
