When I was a single mum it was just DS and I. I am a nurse so don't earn a massive wage but we were definately comfortable. We live in the north so rent is cheap. I could afford a nice car, took DS on holiday every year, we had nice clothes and we were doing great. I met DP who seemed lovely at the time. To cut a long story short he and his DS moved in with us (as my house was bigger and in a good area). Now everything has gone tits up and I really regret ever meeting him. He has tons of debts that I never found out about until after he'd moved in so a massive chuck on our money goes on that now. He works part time in a supermarket and makes every excuse in the world not to better himself, go to college, retrain, look for full time work - he won't do it. He refuses to ask his ex for maintanance for his DS also and I'm just finding it all so difficult. We've had to downgrade the car because of his debts, we can no longer go on holidays. I suppose in a way I'm just looking for a way to tell him I want him to leave 
I feel so resentful that our lives had spiralled downwards ever since he moved in and I don't think I can get past him and forgive him.
