Strain in relationship while TTC?

Has anyone else had problems in their relationship stemming from the stress of TTC? My SO and I never fight-mild disagreements or misunderstandings that we work out right then and there but lately everything is just strained. I constantly feel hurt and he feels like a failure bc I'm not pregnant yet and 'he can't make me happy' and give me what I want. I don't like how we are now. We aren't the happy in love couple that wanted a family anymore bc everything is all about not being able to get pregnant now and the next step......I almost want to stop trying so my relationship can be what it used to. Anyone else have issues and what did you do to fix it? 😥 I never thought trying to have a baby could be this stressful. It's supposed to be a happy time right?
