I want to propose to my partner but im nervous that it might be due to unhealthy "boredom"

Hi there!

I'm thinking of proposing to my partner but I'm not sure if its the right time. We have a healthy relationship and love each other dearly.

The only thing standing in my way here is that I've been in some not too good relationships before. This has got me used to expecting a certain amount of excitement when it comes to love.

Since this relationship is healthy, things are just peaceful (the way it should be). And I'm a bit nervous that my head might see this engagement thingy as a way to spice things up again.

Our anniversary is also coming up soon, so this would be a great opportunity to make something nice.

We have talked about marriage before and we both said that we would be open to it. (So it's not totally out of the blue) And I'm am certain that no matter what I decide to do here it would eventually come with time.

Any ideas on how to deal with the matter?

Thanks in advance!
