Girl I work with we both have a thing for each other

If we work the same shift we usually take lunch together and talk and what not

Recently there was a miscommunication about what time we were taking lunch, I assumed it was clear I was taking it at a different time but she didn't realize that and got upset because she was waiting for me.

Saw her after work and she was acting strange, so I asked what's up. She told me I ignored her all day and made her wait for by herself.

I apologized sincerely and told her I didn't mean to make her feel that way, she kinda gave me the cold shoulder but texted later and said "let's forget this happened ok, and move on from this?

I agreed and once again told her It wasn't intentional, made plans for today to have lunch again

I'm a pretty nonchalant guy but last night I felt like I gave the clingy, nice guy, boyfriend vibes by my whole demenar of apologizing and trying to set up lunch again

Any advice gents?
