You are def not alone! Ive noticed just the ladies giving feedback. I am on the male end of it, and i do believe everybody has there own individual way of dealing with things.
Ive had trust/relationship issues before(for good reasons, aka being cheated on). I feel ive grown a lot, of course some things try to pop in from time to time. Being so far away can def add to extra stress/emotions! Ive reccently thrown a fit myself for the first time about similar issues. Im glad it happened cause i caught myself, and realized i need to correct some things still!
In any relationship its easy to get lost inside of it. I think lot of the problem is expectations, and routines. Say at first you talk here and there, at which point your ok with it. As time goes by, you talk more and more, get use to hearing this person around the same times daily...one day they decide to do something else for a change! You expected them to be there, you i guess that expectation/ almost becomes a need! So lately ive been trying to regain my thoughts to me, not just her all day, cause she def seems to fill lot of that brain space! lol! I dont want neither of us to have an unhealthy relationship, and do need to accept we both live on opposite sides of world, hence needing our own lives as well. Easier said then done! If your missing your partner while your out trying to enjoy yourself, im sure he is too! Dont take it personally, he could be stressed too, or as someone stated before, talking about same things daily..well only so much to say! Enjoy your trip you booked!
Like you were in the process of saving the little money we can for down the road. Def hard when you in school and most your work $ goes to bills!!! =D Im just looking foward to my trip to visit my gf in 3 weeks in the UK. You are not alone, or wrong for feeling that way. Now that i saw myself getting lost in the relationship, it was a wake up call to not let that happen. Puts reality back into check! Be supportive as you can, know he loves you, tell him to go out, keep up the communication! Ive learned that theres no set way for anything! Try to avoid expectations, everyone does things differently, doesnt mean there feelings arent mutual! Good luck!
