Look I'm not against age gaps in adult relationships in general, and he might genuinely like you. BUT he will likely continue to have relationships with underaged people and has likely done so this entire time. You are a very convenient cover by the way, even if he's not fully aware he's using you that way. There are high high risks with P. Someday, and probably not too far away, you will likely be devastated with him. It's ok to walk away from something that feels so good. There will be another. I'm not sure about D, but you should feel much better about the manner and your age when meeting. Don't let your attachments and emotions overrule sense.
