What would you do if you felt like you were in a 3 way relationship?

[Anonymous]

I'm 22 and my partner is 36 and I love him so much he has helped me a lot I have been in and out of hospital since I was a kid with back pain and I had really bad days where I can't get out of bed he has a best friend 56 and we just got a new puppy 20 weeks old (he never helps with) I am in really bad pain he has left me at home with said pup on my own, told me to do washing and left. I am not leaving him. I feel like I'm in a 3 way relationship

I wouldn't stick around if I was unhappy and couldn't find a solution
