We tend to choose and also attract partners with whom we replicate some of the dysfunction in our families of origin. This is also documented in relationship books. What makes two people attracted to each other? I think we've all experienced meeting people and there isn't anything really shockingly wrong - such as being very unattractive or mean and yet, there is "no spark" "no chemistry. And then there's chemistry with someone else. Why is this?
It's not something we are conscious of entirely. In part, the dynamics feel familiar to us, even if they are dysfunctional. We learned certain behaviors in our families that were necessary for our survival then, and are dysfunctional as adults. We also may have experienced emotional trauma, and low self esteem from how we grew up.
We may then seek out people who don't reciprocate our love and attention, just as our parents did the same. Yet, we think if only we try harder, they may change. Well we know from the parent board that this isn't effective.
Also we choose people who seem to match our boundaries. Two people might meet, have a couple of dates but if one has poor boundaries and the other does not- the relationship is not likely to proceed. Poor boundaries lead to tolerating/not recognizing red flags and accepting behaviors that are not kind to us.
If I told him I was unhappy he would tell me that it was a great relationship and he had no problem with it. He would say that we were luckyHow invalidating. He's speaking for himself. The relationship works for him because he controls it and steers it to how he wants it- all about what he wants, but not any consideration of you.
And you have decided it isn't good for you to remain in this situation. You aren't wrong to consider how you feel in this relationship. You aren't happy with someone who is inconsiderate to you, and when you bring up your wishes, he dismisses them.
Other people like "him" but the "him" they see is his social persona and just because someone else likes him, doesn't mean you have to.
You aren't wrong. You are now considering your own self worth.
Once aware of our own behaviors we can work on gaining boundaries and better relationship skills. It is also said that if we leave a dysfunctional relationship without reflecting on our part in it, we may risk repeating the same patterns with someone else. That's a good incentive for self work

before making the next commitment.
