Ring or No Ring???

Anna
My daughters father and I were engaged 4 years ago. He called off the engagement when I got pregnant. We have been back together now for 8 months. I want a ring to wear but he says it's not on the plans. He says he loves me but it's not on the plans. We don't plan on marrying just living together being a family raising our daughter but I would like I ring to remind me of our love n being a family. Valentine's and our Anniversary is this month. So what should I do??
