Says I’m over reacting and he’s not in a bad mood. Or under reacting and ignoring his real problems. Making me really question my own feelings
So he thinks he's got the right answer about what reaction you're supposed to have, then? And he gets to tell you whether you're doing it right or not?
What he's really saying (along with anybody else who says someone is over reacting/oversensitive etc) is that you are reacting too much/too little/etc for his preference. He's saying that, in his opinion, his view on this situation is the right view, and, your reaction doesn't fit, so it's an inconvenience for him.
It's not an objective view he's giving. It's his opinion. He would prefer you to stop expressing inconvenient emotions. His comfort is more important than your discomfort.
Don't question your feelings; you're allowed to feel whatever you feel. A respectful partner will respect your feelings, even if they were illogical or hurtful.
People think marriage is meant to be good all the time, are not married
This isn't true. Many people are very happy in their relationships with their spouses, and don't have any ongoing conflict.
