umm, together a week when he unofficially moved in, (stayed the first night and never left!) - engaged 4 months later, married 12months 4 days after we got together. been married almost 3 years, weathered some pretty intense stuff in there (loss of his brother, family breakdown, miscarriages, IVF) and still very happy with our relationship

i don't think the amount of time you're together is a good indicator of how your relationship will last - it's how you weather the storms that arise as you go along. we have been very (un)fortunate that we've faced a LOT, including DH working away long term, him now facing a degenarative illness, both having major surgeries - we've been through a lot and we're still strong. yeah, we have issues, but it's not about how long we've been together - it's just part and parcel of a relationship (IMO). at the end of the day, we love each other, we're compatible and we're content.

ETA - DH told me we were going to get married the night we got together!
