i have a boyfriend， he is tall and outgoing. he is active and handsome too. i like his look when he is playing basketball on the playground. he is so strong and sharp on the court. he is friendly too. i am happy being with him. i want to be his girlfriend forever.
这句话应该是有前提的，等待结婚的情侣可以说；i am going to be your husband，如果是等待对方离婚的情侣，i am going to be your next husband，
