SO issues ?

So recently I've started feeling like we are growing apart, he doesn't think so but I can feel it. I feel like we are just comfortable and not really going anywhere. We have tried date nights and spicing things up in the bedroom but nothing's working and it's making me question whether I really want to be with him. I think neither do us have ever had a real taste of being single and as a result I know I personally wonder what sex would be like with someone else. Wi don't know what to do cause I love him more then anything but I'm not happy anymore .

Also Lately I've been very hormonal and my mental health is suffering as a result and I'm not sure if that's why I am having these feelings ??
