How do I make it work?

Guess What - if your parents are good parents you trust, then it is highly likely they know more than you do. Trust them and their choices, I wish my parents has been more vocal in their opinions of my relationships. There thoughts on my younger sisters were always dead-on. Pro and CON

You're an adult. Your parents aren't supposed to make your decisions anymore.

Woah. You definitely need some advice. Let me get this straight. Here's what I got from the whole explanation:
1. You have this boyfriend that you seem to really like.
2. He used to be a player who didn't have much of a future, so your parents didn't like him.
3. He's trying to change and your parents won't give him another chance, but you will.
4. You're stuck with the whole question: Will my parents change their view about my boyfriend?

The answer is maybe. It's possible, not completely unlikely. Questions to ask yourself:
1. Do you really love this guy?
2. Can you see a future with him (specifically, marriage)?
3. Was he so bad before that you are just being a pushover, going out with him again?
OR
4. Do you have an opened and forgiving mind, whereas your parents do not?

Now, your parent's obviously care about you. Remember that. Disowning is a little extreme, but it's only because they care. If they didn't, they wouldn't mind you going out with this guy.

What I would do if I had this situation: I would lay low, and respect my parents. Still, I would have a serious talk to them saying that I was a grown adult and I liked this guy. He made mistakes in the past, but he is cleaning his act up. Tell them that you respect that.

Ha! You wrote this six months ago. Ummm well. Oops.

I am a parent. I may not agree on some things with my children but we come to an understanding. parents Intuition. It will always be there. You are an adult, capable of making your own decisions. They may be right, they may not. But it is not about them its about you and what you think. Your parents have got to come to an understanding. They don't know. Its about the present not past.

And even if you decided to further your relationship with this boy and he ends up being the same player he was well then at least you would know.(Making mistakes are good they help make us stronger and learn to make things right) Your parents need to just let go!! Good luck
