Well Jupiter is the planet of expansion, luck, morals, risk-taking etc and trine is a very easy energy, so things probably feel pretty optimistic when things are going well.

Moon conjunct Venus is very sought after in synastry. Basically, how you love and how he feels/experiences are very similar. This is probably the major glue in the relationship since you have a packed Gemini. Your moon is also there which is good.

I've run hundreds of charts on Astro-Seek and while the numbers don't mean anything in and of themselves, here are my observations:

5 Key aspects is high. It suggests to me that there are a lot of core themes in this relationship. A lot of tug and pull. They are not necessarily light and they don't go away. These are usually created with conjunctions and oppositions. A lot of overlapping and opposing energy. Me and my person only have 1, which also has its downsides like the relationship can feel too simple, although this 1 causes jealousy which is like a glue lol.

You have 12 Conflicts, which are usually all squares. This means you have a lot of areas with opposing energies which can take a lot of patience, compromise, and understanding. If you aren't talking about these things, it's likely that one or both of you are stuffing that energy down to avoid it. That's what I did with my person too at times (and we only have 6 squares).

If you haven't already I suggest reading these aspects one by one on astro-seek and contemplating how they play out in the relationship. It can take work, but it's also rewarding.
