Weed - should I just accept it?

Hi I have been with my boyfriend for 7 years and we are due to get married next year. Only problem is he smokes weed ever day and I hate it. His argument is he has a good job (over 40k) so the weed shouldn't be an issue to me. I also have a good job on nearly 30k so we have a promising life ahead of us. My issue is I can't live with the fact he may still smoke weed when we have kids. He says he'll stop when we have kids but I don't believe him. I feel so strongly about this. I know it could be worse he could have an addiction to a stronger drug or have a crappy job but I can't live with it. I've tried to talk to him about it several times and he refuses to listen. He makes out I use the weed as an excuse to argue with him and that' im being controling "it's ur way or the highway" he said how would u feel if I told you to give if drinking it's the same thing. It's not as I drink of a weekend not every day. I'm 28 this year and he is 30 I thought he would grow out of this by now. I want to have a baby and I just can't until he quits. I feel like I've wasted 7 years with him and don't know what to do. I Tried to talk to him yesterday about it and he refused so I've threw out his weed his bongs his weed tray and grinder. He's gone absolutely ballistic saying I'm a horrible person etc. I just felt like I had no choice. I know I've gone about it the wrong way but he refused to listen to reason

Yes I trust him completely in everything else. He is a good man but the weed does send him aggressive when he hasn't had it in a while and a Unresponsive when he's had it. He says I should just accept that this is who he is. I guess you should not force a person to change if they don't want to and if he's not going to change and I won't accept it we have reached a stale mate
