My husband is in his forties and sends warm messages to his first lover all day. He said he and he were just soul mates. Are they normal like this?

Don't say the word divorce easily between husband and wife, it will hurt each other's feelings. Your husband's behavior is a bit unacceptable, but now the relationship has not developed to a serious degree. You should calm down and talk to him. Look at your age, have you been married 10 years? If you have something to say, maybe it's just spiritual satisfaction, just like your husband said. Don't be too persistent, it's not good for you and your family!
