Relationship advice

I need some advice.

I absolutely love my boyfriend and he is absolutely so perfect for me and does everything he possibly can to keep me happy and I know how much he loves me and would never do anything to hurt me.

But I get in these funks and make myself believe that he doesn’t want to be with me or there’s somebody else when I know that’s not the case.

He brushes it off as my crazy pregnancy hormones and always reassures me that he’s here for the long haul, but I just can’t shake this feeling.

It’s like when you feel something is too good to be true so you try to find a reason why it’s not.

Does that make sense? Does anybody else get like this?
