<human>: I've been with my SO for just over three years and last night told her I wanted to end things and break up.

We have lived together for just under 3 years (moved in quite quickly) and things were going good, we got on well, liked our respective in-laws etc. Not too long ago I started to feel like the 'shine' had faded from the relationship. I didn't have the feelings for her that I had for girls in previous relationships I had, and I didn't feel as though this relationship would be 'the one' for evermore. I didn't feel like I did at the start of the relationship basically - felt there should be 'more' somehow.

So, last night I told her that I still have feelings for her but that I am not 'in love' with her any more. She took it very badly - she said she had no warning of this and I had totally blindsided her. I feel terrible and am always the kind of guy that hates to upset other people.

I know I've made the right decision, but now I just don't know what to do. It is my flat that we live in (rented) and she really has nowhere else to go at the moment, so we will be forced to live together for at least a little while.

I'm not sure how to help her or how to deal with this situation.
Any advice gladly welcomed, home is not a nice place right now and it's my doing.

Give me a shortened version of the text
<bot>: I broke it off last night after 3+ years, we live together and I don't know how to help her/approach this.
