Lost respect for my husband

We have been married for three years, together for 7 years and have two kids under two. I feel like an awful person, I constantly blame him for everything, I think the worst of him and although he has his faults I realise it’s mostly me. I don’t get much out of our relationship, we’re very different people and more and more I think I don’t need him and work out my stress on him. But I want to work on our relationship for our kids. Question is, should I be brutally honest about the way I’m feeling realising it will hurt his feelings massively, or will that be counter effective if I want to save our relationship? Please I need advice, I want to get through this…
