Feeling insecure when my boyfriend goes out? LDR

Hey ladies, I need some advice. Thank you for taking the time to read!

I have been in a year long LDR with my boyfriend. He is in FL and I am in AZ. If it’s relevant, he’s 31 and I’m 23 (24 next week!) He has an extremely demanding job in the military and I work in restaurants. So, we blow off steam in different ways. I am around people 24/7 and cool off by having chill, alone time. He likes to be around his friends and think positively and be out and about.

I’d like to start out by saying that I am moving to FL to live with my boyfriend next weekend. My concern, like the title says, is his partying- or rather my insecurity when he does.

He hasn’t ever given me a reason to think he is up to something sneaky. I will say that I dated a guy (in high school, my first “boyfriend”, I was so young) who would break up with me on Friday afternoon and then go party on the weekend to pick up girls. He’d completely ignore me and post pictures of himself with these girls on MySpace (yes, I know). Then, he’d want to get back together with me on Monday morning once he was done.

I have this irrational fear that this is what is happening now, even though I also know that this is NOT the case. I know he loves me and wants a future with me, and since we are in an LDR he hates just sitting by himself and would rather be out with friends. I totally understand and am on board with that.

I guess my question is: Has anyone ever dealt with this type of insecurity? How did you get over it or deal with it in a healthy way as to not push your man away? Also, if you were or are the more “social” one, how would you like a partner to go about dealing with this so that you feel like you are compromising without having to change yourself?

Again thank you for your help. He is my only serious boyfriend so I don’t have much to compare it to.
