We started spending every night together after 2 weeks of dating. I moved 40 minutes away from where he was so we'd just stay at each place every other day for 2 years. Then we broke up for a few months (note that we spent 1 day apart in those 2 years). When we got back together we moved in together and I think the longest we've been apart in the last 3 years was 16 hours. lol
