Heartbroken

This weekend has been horrible. Boyfriend broke several boundries. To the point i could have been 100% justifiedin walking away. I am not ending it but things are changing drasticly and he knows this.is the last chance. There is no.more mistakes, bad choices, or trying. His actions this past weekend shattered any hope of us having a child together. I will be calling my doctor to get on birth control soon, he and i will now ise condoms if we sleep together. I wanted to marry him and spend the rest of my life with him. Now i am questioning if we have a future at all. I wont be giving more details, i'm not looking for advice or anything i just needed a place to say this. I cant talk to friends because they are also his friends and i wont bad mouth him to them.
