My husband & I went through nearly 4 years of him working fifo. The first half he was home a wk a month & the last half only 2 days a month. Whilst not strictly long distance we still rarely saw each other. Unfortunately long distance doesn't work for everyone. Some ppl come back together & find they can't get in sync again, others cheat, some get depressed. The hard part is no one knows how their relationship will come up till the end. I know it all sounds obvious but maybe you should try couples therapy, that way someone else is there to help mediate your discussion & give advice?
