Undecided

I have been in a relationship for 11 years and married for 2.  My husband is very loving and can be annoying sometimes. There are things that he does that disturbs me. He is now inquiring about us having a child of our own. I'm scared because he's 46yrs old and I'm 33. He has knee problems and I just can't see him keeping up with a baby. He works 3rd shift as do I, but he is always exhausted. When we watch a movie or go to the movies he falls asleep. On weekends he don't want to do anything but go out to eat. I'm currently in the gym and working on my body for my own personal reasons. He hates when I start to lose weight because he gets so insecure. He always tries to offer me my favorite dishes and push me away from the gym. He won't go to church with me so I decided to stop attending. I do most of the work around the house and I am also a foster parent. It can be very difficult but I love kids so much. I always have to tell him to take the trash out on trash day. We also have 2 cats and four dogs that I have to take out for walks or it won't get done. If I don't feed the animals it won't get done. It is becoming a lot for me. I love him with all my heart and he has gotten better but I just need to hear from someone... I need some advice. Please don't be harsh. When I talk to him, he helps out but sometimes I really feel like I'm being taken for granted. The thought of leaving just makes me sad because I love him so much. How do I get him to go to therapy if he refused to go? Help me out somebody. Thanks in advance.
