I feel like I love my partner, but I also love my ex.
Are you just bored in your relationship?
Yes, I'm tired of repeatedly resolving the same issues.
Feelings are difficult to control but it is not okay to be in love with two people at the same time. It is not fair to either of them and could hurt them both.
I'm just having feelings for them both, I'm not going to do anything about it.
Even if you don't think you're going to act on your feelings, being in love with two people at once can complicate your relationships. You should figure out which relationship you want and then pursue it, instead of dithering between the two. If you remain in love with your partner and your ex, one of them is going to get hurt.
