Our relationships are a good mark to where we are in relation to our spiritual path (whatever that is). If your partner was unhappy with you and decides to leave you for your best friend. How are you going to feel? Probably like crap. But if you really loved them you would be happy for them regardless. Now this is imho practically impossible, unless you're enlightened haha.

So how do we deal with partners and our attachments? We just keep at it with our practice whatever that may be. When you keep the soil well and water the seeds often, then good fruits will spring. So see how you act towards your partner. Are you jealous at times? Are you angry? Are you happy? Are you indifferent? These are perfect opportunities to use mindfulness. Watch how you feel, what you think, and what you are doing. How does your body feel when you feel jealous, angry, or happy? Etc.

The people closest to us are our teachers. Since we are around them the most, what we say and do matters the most.
It's often we say we love and we do for the most part love the people closest to us. But we often treat them like "shit".

Most romantic relationships end like that. One moment you love them. One moment you hate them. Given some time all things see the opposite.

It is what it is though. You shouldn't totally detach from people or desires, because that is the other extreme. It's okay to have desires. Do they benefit you and others? Is this desires worth it?

It is all about balance. The middle way. Not detaching. Not attaching. Just being mindful of what arises and falls. Then from that vantage point you can choose what you want to do. But make sure your intent is clear and that it isn't going to harm you or others. With that condition, right action and speech come naturally.

Keep meditating!
