<human>: Normally I wouldn't be insecure about a development like this in a relationship, I am generally pretty well versed at navigating my way through.

The problem is, I broke up with my ex boyfriend of 2.5 years almost 2 months ago and don't really feel I am ready to just jump back into a romantic relationship. My ex boyfriend lived in the same house as my roommate and I for about 6 months before we split. I haven't really seen him since and the breakup has been exceptionally smooth and very mutual. 

I am concerned that I may unknowingly lead on my roommate. It's a pretty obvious and mutual attraction and we have been spending A LOT of time together over the last few weeks. We genuinely enjoy the company of one another. 

My ex is no longer a part of the picture and he never will be, I am just worried I am not giving myself enough time to recover but also feel so happy and content when I spend time with my roommate. I am afraid of what might happen if and when we take our relationship to the next level. 

What should I do?

Can you condense the text into a few key points?
<bot>: Just got out of a long and serious relationship and developing feelings for my roommate, need advice on which direction to take next.
