Inviting Chris to pool party at Adrian's house

Hi, Chris. How are you? It has been some time since we met saw each other last summer. We had a great time together, hadn't didn't we? The truth is that I appreciated every minute alongside you. I really miss you. (<--This phrase is fine, but in some English-speaking areas, it's usually not used between people who are only friends, especially if both friends are male.) By the way, did you hear about the pool party which that will take place in at the Adrian's house tonight? Every single friend of mine is going to this party, so I thought how delightful it would be if you could accompany me in this wet adventure! (<--Grammatically, there is nothing wrong with this, but these words can be interpreted as though this is an intimate invitation. If that's what you're going for, no problem, but if not, it's better to reword it so it sounds more friendly and less intimate.) So, What do you think about it? Can you give me the honor of your company? (<--Same issue as above) Just tell me what time and place should I pick you up, okay? I am looking forward to seeing you again!

Nicely written again, Henrique. I'm not sure if this letter is a friendly or intimate invitation though, because a lot of the words/phrases you used imply that you're interested in Chris as more than just a friend. If that's your intention, then this is fine; however, if it's just a friendly invitation, you'll need to change what I've highlighted in blue. I hope this helps =)
