Big red flag...BIG...
His history, and these little changes you have noticed. That's not uncommon for an abuser. They put on a good front...play the charming, loving, romantic boyfriend. Once you're hooked and loyal to him, the real guy starts to show.

It always starts small...I encourage you to read about the cycle of abuse. Tension increases until the incident happens. Then he's sorry, loving, romantic. he makes promises that it will never happen again. Or he might say, "well if you had just...xxx...then I wouldn't have done it." somehow displacing the blame onto you. And then you're confident and happy...honeymoon period. Then the tension slowly begins to build again. And then it all happens again...

I regret having not listened to people who tried to warn me...the red flags that I saw. 13 years later, I am out...but we have kids and he still has control. He didn't ever physically hurt me...but he was controlling, manipulative, anger issues - throwing things and holes in walls, and then he started raping me.

You deserve to be loved and cherished. and treated like a princess.
