<human>: Can you give me the gist of the text in a nutshell?

So backstory(sorry this is wordy):

We've known each other for about a year and 3 months. This is the second time dating my SO(M 18). My parents knew about it the first time when I explained it to them about a month into us dating. They were both fine with it and pretty supportive in general. So we had a pretty bad breakup and my parents knew about how upset I was about it. But I didn't tell/haven't told them how I've been feeling and why we got back together. I'm sure they know we're talking on a regular basis again but I haven't explicitly told them that were dating because they're not necessarily his biggest fans.

The current situation:

My relationship this time is really solid and so much more mature than last time and we both know that we're in it for the long run. He's coming back to the States this summer so we want to meet up and he invited me to his best friend's wedding in Texas. I live in Iowa and he lives in Tennessee. I plan on asking my parents for permission? More like a blessing I guess? Because my thoughts right now are that I'll be 18 and even if they don't want me to its important to me and it will be hard to ever find time other than this summer because I'm starting college and he's going into the Army.
<bot>: I don't know whether to keep my parents up to date with my relationship or just do my own thing with it.
