My first boyfriend invited me to dinner. Should I go? Ask god for help

Go ahead. No matter how he feels about you. You just need to talk to your husband. Your husband will not stop you. Marriage is based on trust. But you can go out for dinner with him once or twice once in a while, but you should avoid suspicion a little. You can invite a friend who is familiar to you and him every time you go. So your husband won't have any ideas, and he won't say how to be jealous or anything.
