Good Bye again

I hate to say good bye to people but for some reasons seems like in all my life i have been saying it to too many people already specially to my boyfriends. I even started to think that this is a karma thing or a "sign"and i try to analyse if i need to learn something from it and maybe it will stop happening. I belive if someone that you love want to go then you should let them go, i always did that and support them in their decision to travel or move away but i leave heart broken. They promessed me to keep in touch, to try the distance relationship,etc and only works for 1 month ( 4 weeks), the funny thing is that its "ALWAYS 1 MONTH".
Today, i took to my bf to the airport. I thought it will be worst but i was and i am ok, i do support him and want him to be happy and if is mean to be, we are going to be together. But, i can not denied that i am still thinking on "1 MONTH" and then it will be over. Of course i dont want this happen but it always did happen to me. Oh and i forget to mention, after the 1 month i stop hearing from them until 1 year later when they come back with the famous "i love you" i want to be with you but then its too late. I never got a good explanation of why they stop contacting me, i wish i can understand that.
I am trying to keep it positive and think that my bf will be different and maybe i will learn with him what is the "GOOD" distance relationship ...
Today is my second day of training...
