Aw hun, I really dont know what to say. It's your desition at the end of the day and no one will judge you whatever you decide.
It's very difficult. Maybe you could give your oh a few weeks for it to sink in and he might come round? He's prob just in shock right now!! I'm sure deep down he wants you to keep this baby. Maybe he's unsure of the extra strain it's going to put on your relationship? But hey lets be honest, I think if you got rid of your baby (the one you so desperately want) thats going to put even more of a strain on in the long run. I think you know what you want to do, I've got everything crossed for you he will change his mind

Will be thinking of you hunny, big hugs x x x x x x x
