Here are somethings to consider.
1. Some of your repair items (appliances, wear on roof) don't feel reasonable to me. HVAC and chimney certainly are. Electrical depends on what the issue is.
Now, if you are using repairs only to win your position with your husband, it might be that you discuss more about what you really don't like about the house anymore if it is the design, lack of light, room sizes, avg electrical or gas bill (don't forget to get that).
Know that lots of times buyers have buyers remorse about a property or thing at some point. There are certainly ways for you to get out of it. Now is the time. Your realtor can tell you how she/he recommends. If they are reticent about it, seek another realtor's opinion.
Then, have you thought about buying new from a good builder. Hopefully, a house that's already built. They would give great discounts through negotiations. Houses don't depreciate the moment you get them like cars (except for add ons like pools and such). Builders may have better deals out there with warrantees and throw ins. Course, new home developments tend to go with smaller lots and similar space plans that look like a rectangular box on its end -- depending on the price point.
2. Your inspector strives to note anything and everything to give you your money's worth in negotiating for repairs. No one expects you to list all those things must be fixed or get money to repair them. You mentioned the refrigerator. Most homes don't sell and include a refrigerator. If they are leaving it behind and you don't want it, tell them to take it. The HVAC and chimney may or may not cost a fortune to fix properly. Depends.
3. Your realtor has a vested interest in your concluding any sale. They gain a commission on it. Do not rely on them for advice on whether to go ahead or not or whether a repair request should be included or not. They may tell you what's standard in the market today, but take their advice with a grain of salt.
good luck.
