I have had an on and off relationship with my boyfriend for 3 years and we have 2 kids. We break up then when we get back together he is really in love with me. Then a couple of months go by and i don't get the same attention. I want it to work out. His mother and I don't get along very well. We also live with her, her health is very bad and he takes care of her 24/7. I feel like i am in the way of their lives. what should i do?
