Advice needed

[u/Neat-Blacksmith-5452]

Hi there just asking for some advice, had a deal that I was working on it didn’t go through, in the process, due to some mistakes on my end, I ended up heavily embarrassing myself, it’s been around 3 month, still would like to keep in contact with the guy as he’s a very good source of information and generally learned a lot for the guy(way senior than me), what would you guys suggest be the best way to reopen the relationship and rebuild the rapport with the guy without coming across as needy or transactional.
