There are good and bad relationships. With respect to all you women who have been used or abused or cheated on you need to take accountability for you and stop pretending to be mystified by someone who is behaving very consistently like someone who doesn't want to be in a relationship with you.

Spend less time wondering about his head and focus on you. Think about where your head is when you continually go back for more even though it lacks so much and there are so many other nicer men out there who would want to get to know you and be with you.

It's not at all normal to want to be with someone like this. You've done it for years! Solve that mystery. Is it because you have such a short memory? Lack confidence? Hate change? Scared of being alone? Something drives you to tolerate this extremely bad and selfish behaviour and you do not have to tolerate it at all.

Relationships with relationships can be full of difficulties. Some of them try to influence you or control you, in a way that you would not tolerate from a partner and believe that you must persistently please them and do as they say because you are related and always will be.

Relationships can be a pain but even more with relations you are stuck with  like father or mother. My own are difficult species, specifically because demanding and long term difficulties. Both have things going on with them with mental health and drinks. They can be hard to live with and even just hard to be with if not live with. Neighbours not speak to them.

Seeing the above bits, yeah, some family are terrible, you cannot choose them. I spend lots of time with friends instead. Family were too full of themselves and finding fault all of the time, in ways that no friend would dare cause they know you would disappear if you did.
