Co-workers

So i have been having this debate with myself for a while about dating coworkers...

I usually have a very strict no coworker policy, my daughter happened because i dated a coworker & well he was not the most ideal best man to date, but i guess there was something that i liked...needless to say i haven’t been interested in dating a coworker until this one girl i Work with tried to give my number to this guy i worked with a lot last year...i think he is pretty cute & i honestly love working with him, tonight there was something that i felt just looking at him & i honestly think it cause that’s all we talk about is him, but idk...

I usually wonder why anyone would date me there is nothing special... (if you can’t tell by this horrible comment i have been abused into thinking that i am not good enough & that is kinda part of why i am single.)

Please someone help me out with this mess...
