what should i do

About 5 weeks ago I met this amazing guy at a bar and we hit it off straight away and I have honestly never felt so comfortable with someone before. Towards the end of the night he asked to see me again and gave me his number and told me to text him the next day. I wasn't sure what to do because I had only broken up with my boyfriend a week earlier and things still felt pretty raw and I didnt think i wanted a new relationship this soon, so I decided to not text him back. Anyway, 5 weeks later I have  pretty much completely moved on from my ex and I am regretting not texting this guy back so much. Is it definitely too late to text him now? I would feel kind of awkward texting him after all this time and I sort of feel almost rude making him wait 5 weeks so I'm thinking maybe I should just leave it and move on. What would you guys do in this situation? Help please!
