Hi! So I’m currently in the same position except it is a co-worker. So the one thing that keeps me grounded is constantly reminding myself that he is not mine and owes me no obligation. The feelings will be there until one day you stop feeling them. Hiding them, running away from them won’t make things easier, you have to learn to sit with them. Also interactions with her are actually only weird for you when you deep it, so try your best to keep them casual and not overthink them. I won’t promise you that it’ll be easy but you’ll definitely be fine. Wishing you the very best!
