no support from husband and friends

Ive been trying to workout for a few years now and it never goes as planned. I always try with my husband but he tends to quit after awhile. Ive recently started working out again by myself at home without the hubby and i feel like i have no support. He says he wants to workout with me too but he cant because hes going to get back surgery soon. But now i prefer to only do it by myself. I eat clean most of the time and i would cook for both of us. My husband is a very picky eater and gets tired of eating clean very fast. He cheats very often and it effects me because it makes me want to cheat. Of course i love eating out and eating junk food but im trying to be disciplined and stay away from those foods. He makes it so much harder because he always gives in. At the moment im having to cook different meals for him and for me because hes tired of eating healthy which makes it harder on me becausehe doesnt help out with cooking either so im stuck doing everything. What bothers me too is that our friends have alot of parties and things like that so we visit them often. Everytime they offer me food ill say "no thank you ive already ate" because i dont want to offend them by just saying no i dont eat that or no i dont eat unhealthy foods. They all know i eat healthy but dont know to what extent. They take offense to it and give me looks like im crazy. I get mad because i dont go telling them they shouldnt eat this or that. Or they automatically assume im on a diet. And if i say im working out right away they question me as to why. They say i dont need to lose weight that im already skinny and from there i have to explain that im not trying to lose weight. I lift weights to gain and to be fit i dont want to lose weight and be a stick. But they dont understand my lifestyle im trying to live. And my husband gets mad at me when i deny their food because im offending them but i feel like theyre offending me by not respecting what i do or dont eat. I have no other friends on the same boat as me so its hard because i have no one to go to for advice or support so thats why im on here venting my frustration. Any advice? How can i find people that are into the same lifestyle i want. I dont go to he gym because i cant afford it. We have gym equipment at home so thats what i use.
