Hello Ammee, an addiction can come in any form and in this situation it's with your partner who smokes weed but unfortunately changes his personality when he's affected once under the influence of this.
To him he is not doing anything wrong, but what he does't realise is that he becomes a different person.
To give up when you first met can be normal and is what can normally happen when two people meet, so he can survive without it as your relationship develops, but unfortunately old habits continue once you begin to know each other and with some people it changes them, unbeknown to them.
I can't say what should happen, especially when you love him, but if he was happy smoking it then you could love two people, at the moment you it's two different people, one which you don't like and this makes it difficult for you.
Perhps when he does smoke you could mention to him that you don't like how he changes when he smokes and spend the night with a girlfriend.
If you keep doing this then he might wake up and realise.
