You two are basically strangers, you don't know each other at all, you don't live in the same place or if you do it's just out of necessity (more practical to fuck) and it's not like you actually live together per se. You each have your own separate lives. You hardly talk to each other. Y'all couldn't say a single thing about the other to save your lives. The only two guarantees are that :

- She isn't having sex with other people
- She's having sex with you almost everyday

Is this a relationship ?

Now because most of the answers are gonna be yes I'm gonna ask a follow up question : How would such a couple raise a kid ?
