My SO/children's father and I have a real rollercoaster relationship but we have can to the realization that a lot of people wouldn't even deal with half the stuff we've experiences in these past 4 years together. We might not be in a relationship but we still together lol. We still call each other by our cute lil nicknames and babe along with I love you's. He drives me crazy but I wouldn't want it with anyone else. He's been my best friend for just about 11 years now and he ain't going anywhere 😂
