So me and my boyfriend have been together for over three years now and recently I've felt like there's something missing and like the spark has gone in our relationship and its gotten to the point where i cant even look at old photos/texts without feeling depressed that we'll never be as happy as we were back then again.

I've brought this issue up with him once before briefly but he just told me that we're not in the honeymoon stage anymore and we're settled and that he didn't feel like there was anything wrong with the relationship. I'd felt settled with him though and i was happy and the relationship didn't feel dull and like it had no life to it like it does now.

We just never know what to talk about with each other, i never feel excited about seeing him, most of the time neither of us are in the mood to have sex and i just feel like generally the relationship has gotten really boring and that we have started taking each other for granted. It seems like he's more interested in his friends too and we've started arguing a lot more with each other and then because of all this I've been feeling like i'm drifting away from him.

We both still love each other a lot but i just feel like we've both really neglecting the relationship.

What can i/we do to reignite the spark in our relationship? to make things less boring and bring back all the excitement and mystery to our relationship?
