So many advices, so many thoughts in my head

Hi ladies! It’s so many things I have in my mind and I don’t even know where to start... to the married couples or living couples: I’ve been living with my man for almost 6 months. We’ve been through hard times when he was an alcoholic and now he is doing great after rehab. But, I don’t know how to cope myself in some situations. He is great and I love him to dead. I know living is difficult, am I the only one that sometimes wants to live alone again? Lol 😂 when I wanted to move with him, I told him to accept my cat: Mochi. He loves him , but after we adopted another one: Milo. When Milo came home, my msn went to rehab for a month, when he came back home, Milo was scared of him and until now, he runs away from him for not reason. I don’t know what to do with their relationship, they hate each other and my man complains all the time about the cats and more about Milo. That situation makes so uncomfortable. Since my man can’t drink, I can’t drink around him either and not booze allowed in the house, I don’t even know what to do, sometimes I need not booze to relax me. I learned with him how go be very patient, but sometimes I’m afraid to lose it. All his friends and family love me, Im his support and always helps him in everything. I’m his first great girlfriend in his life lol 😂, the other ones were big bitches and abuse him mentally. If you question me, am I happy? Yes, I am very happy with him. But, is it normal not to be happy all the time? What else can I do for him to love my cats ? He doesn’t want to feed them or be close to them and I feel my first cat Mochi is getting scared of him now, he snaps once in a while and my cat is not used to. Also, my man is now OCD , trying everything to make it perfect and sometimes I don’t want to do anything, specially before work. Most of the time I’m cooking, cleaning, laundry and everything. But because he is not drinking now, he needs things to do to keep him busy and not want to find alcohol as a remedy of boredom. God!! Any advice... i hope I’m not the only one that has perfect relationship, but once in a while hates their boyfriend in a good way! Thanks for reading
