she thinks she's the ldr expert

so there's this girl I came to know who currently is in a long distance relationship. I don't know what is about her but it irritates the hell out of me when she thinks she knows everything there is to disprove any arguement about not trusting your partner while being long distant. I mean I know she's a human and she has feelings but she's just one of the people who irks me to no end. How did I come across her online profile you may ask? The answer is simple. My last relationship was a online one and I admit I was the one who was stupid and thinking it'll last when my ex-boyfriend didn't talk to me after three months of meeting me. I learned my lesson and finally got the hint and finally broke my end of it a year and three months after pursuing it. Now I know it doesn't matter how long a couple has been together, all that matters is how much you and your significant other have been through. But to me, it seems like all she cares about is proving everyone in the ldr community how long they have been together. I think once she is granted her immigration visa and get married to her boyfriend that she supposedly loves, she'll realize that after a couple of weeks/months that living together with someone all the time will drive her insane and the two will break up.
