<human>: Condense the text into a few key points

To make a long story short i have recently ended things with my gf of 4 years. its been just over a month apart and my only regret was not doing it sooner. 

it has been a long time coming and no matter what i did i just could not be happy and was mentally checked out of that relationship for a year, maybe even more. 

i started a new job recently and met this girl there. she knew when i started that i had a gf and would only talk to me at work for a couple of minutes a day. she never flirted with me but our conversations began to increase over time and it is clear that there is a connection. 

this co worker knew how long me and my ex were going out and knows that i was never fully committed to my ex and now she has started talking and texting a lot more. she is now talking much more and openly flirting with me and i definitely want to ask this girl out. 

the problem i am having is that she knows i was in this relationship for 4 years and she knows that i have only been out of it for a little over a month. i really do want to ask her out on a date, but i dont know when a good time would be. i dont want her to think that she is just a rebound and i also dont want her to think that i am an asshole that gets over someone that quickly, but she has been initiating texts during and after work for the past 2 weeks now and i dont want her to think i am not interested. it seems almost too obvious that she wants me to ask her out. 

i am just having trouble with timing, especially with valentines day right around the corner. should i ask her out before valentines day, ask her out for valentines day, or wait even longer like june or july to not give her the wrong impression. 

thank you for your help in advance! 

also i am fully aware of the risks about dating a coworker and am more than willing to take them for a chance of going on a date with her.
