What do I do

Amy • Been with my love since 2/26/2010
So talk about being confused! I had a miscarriage and after that my boyfriend didn't even want to talk about trying again. Now we are talking about a baby a lot again he said yes he wants one but doesn't want to cumm in me but will withdraw and he says if it happens it happens and I'm over here like look if we aren't trying then I'm going to go back on implanon and either we have a baby or we don't. He said he is 50/50 on wanting one I'm over here at 100% but I feel like he is playing with my emotions , so I am going on implanon next week because I'm over the back and forth, but deep down I don't want to. Advice please, be nice!
