<human>: Can you provide a brief rundown of the text in within 3 sentences?

I used to work at a family portrait studio for almost a year with an awesome crew. This specific coworker (we'll call him Jim) and I hit it off and work great together. This past March I shot my first wedding and asked him to come along as my second shooter. Because we worked so well together on that project, he asked me to be his second for a wedding a few weeks ago and it went even better than the one before. He then asked me to be his second for most of his future weddings and I agreed.

Now. I have a boyfriend of 3 years and he is a married homosexual man with a daughter. He knows of my relationship and has met my SO. Last night Jim and I were chatting about my most recent photography project and more and he sent me these messages:

"I would love to catch up with u one evening when we're both free maybe for dinner and a drink (my treat) and would love to talk about partnering for weddings maybe and negotiating rates to maximize both of us and get u the most exposure.

Would u be interested in grabbing dinner , to talk, maybe talk future projects where each one of us wants to see our self within this next year. We can chat about rates , future projects maybe partnering for certain projects etc. But think a dinner and drinks on me would be a good starting place. I'm so grateful to have u as a friend and I know how we work together and believe we can discuss business opportunities.

Hope all that made sense.
It's all late and getting tired but would love to take u to dinner and drinks to discuss many opportunities for both of us as a team."

I am not sure if this is a normal thing to do or if I should accept or reject his invitation. Or maybe even accept the dinner invitation but turn down drinks because I will have to drive myself home afterwards. Or suggest just going out for coffee instead?
<bot>: Future wedding photography partner wants to take me to dinner and drinks to talk about our partnership and catch up. Should I suggest coffee instead, accept, or reject invitation?
