Is it unethical to stay in a toxic relationship...

until you’ve finished school?

With the way things have been going, I honestly see no future with him. He’s disrespectful, uncompassionate, prideful and other things that make him unattractive. We’ve been married for three years and have one child together. Since the beginning of our relationship there’s been a bad habit of him fucking up, apologizing and then me “getting over it”. At this point I’m so unattracted to him. I continue the relationship as normal but I know deep down that when I get back on my feet I’m leaving him. I could move in with my mom, but I don’t know if it’s worth using my savings to move from WA back to FL. He’s military so there’s also health insurance that I’ll be giving up. He isn’t the most horrible person, but like I said he does have a bad habit of disrespecting me. For example the way he talks to me sometimes, telling me to shut up, calling me bitch, he’s not understanding, being competitive, being over dramatic, the list goes on. This is not daily or even weekly behavior.

Back to my question, is it unethical to stay with him, knowing I’m going to leave him after I’ve reached my goal?
