One of my friends that I know is in a long distance relationship. They have been dating for about two years. They are youngsters, too, (I included this, because its a lot harder when your younger and in a long distance relationship, cause you have to ask you parents for money for a plane ticket, etc.) it took them a year to finally see each other, and when they finally did, they loved each other sooo much and they grew stronger. BUT... what he doesnt know is that, she had cheated on him with two different guys in their first year together. I had asked her why she cheated, & it was obvious, her long distance relationship did not work out, cause they never seen each other, and never had a memory but over the phone with each other. So she cheated, got some d*ck from other guys, and still stayed with the guy.
When they finally met, i believe she changed and finally decided to commit to him. I dont know if he is cheating on her, or talking to other girls behind her back, but it would be sooo easy to do so. She wouldnt know. Just like how he doesnt know that she did to him. But from how I see it, long distance relationships will and wont work. it all depends on how the partners communicate and commit with one another. If there is none, then of course there is no relationship.
