Ladies Am I Wrong?

Kenya
So right now I be struggling with working out a losing weight . I'm not really big but I gained weight and I don't like what size I am and starting to feel insecure with my body because I'm not used to being this size. I have a gym membership with my boyfriend but I barely work out cause I can't stay focus and I don't have structure. I used to be in cheerleading and dance so I never had to go to the gym i was just always active and in shape so going to the gym is new for me. So I asked my boyfriend for help to, I want him to be my workout partner so I can stay focused and create a routine but he said no. He said I have to do it on my own . But I'm upset because I believe that he should help me because he knows what he's doing, I don't. If I'm asking for help and getting a trainer is too expensive should I be upset because he doesn't want to help? I mean he doesn't have to help forever I just want him to help me in the beginning so I get the hang of what i should be doing and create a routine then I don't have a problem working out on my own. Should I be upset ?
