lies and abortion..

so I found out I'm pregnant. yay!!! would be yay but last time we found out we went and had an abortion, wanting to do the adult thing, due to situations and being a little older. I don't believe I'm strong enough to do that again and if I tell him I do believe he would want to abort. do I tell him? and if so now or later? I'm only about 6 weeks. i Love him but I'm so confused please help!
