OP, you need to have this as a rule to live by.

NO romantic relationships with people at work - EVER.

No crush, no "finding someone attractive" - nothing of the sort.

Park as far away from her usual parking area. Stop stopping directly outside to put on sunglasses or earbuds (looking like you are waiting for someone).

Put it in your head that any romantic relationships have to come from contacts you make OUTSIDE of work. Never ever attempt to create a relationship with anyone at a company you work for.

This is actually good advice for anyone who wants no problems in the workplace.
