<human>: My significant other and I have been together for 4 yrs since August. Everything has been really amazing for a while. Yes we've had our arguments, but it was never anything terrible. He is everything I have ever wanted. 

Recently I moved 40 min away from him. This wouldn't have been a problem but his car finally broke down and he is currently saving money to get a form of transportation. The only way for us to be together is if I drive. However both of us are consumed with our jobs. The only day a week we can be together is sunday. Talking on the phone is tough because I have time when he's asleep or at work, and he has time when I'm asleep or at work. 

Lately its become so bad that we've only been texting each other. Not often I may add. I've always been afraid of him cheating due to past occurrences. Nothing physical, just super friendly (and secret) chit-chats with other girls. Came upon it by accident, he leaves his fb open on my computer and messages popped up. 

This hiatus of talking and constant suspicion of cheating is wearing me thin. I think I'm falling out of love with him. At my new job, I met someone. Even though nothing has been said I'm already fantasizing about this new guy and slowly developing a crush. Should I try working things out or just call it quits?

Can you succinctly summarize the text in 1-3 sentences?
<bot>: SO and I barely talk. Falling out of love (possibly) Starting to crush on a new guy. Should I work to save my 4yr relationship or just call it quits?
