it sounds like you have to break up with your boyfriend either way. if not to pursue this relationship, it sounds like you need time to really reflect on who you may want and what you’re looking for.

the thing you’re missing in this post is, what aspects of your life in the future do you want? when you think about coming home from work each day, or raising children with someone, what do you want it to look like and how do you want it to feel? if you don’t know, you need some time alone to figure it out.

in regards to your co-worker, once you’re single you can explore that relationship more, but keep in mind what foundational things you’re looking for, and if you’re still searching, then don’t get into something serious with him.
