Decide what you actually want here. Then decide what is realistic. Then develop a strategy to get you what you want and modify as you go. You can do this and yes, you can achieve a much better family situation.
If you want the close relationship that you formerly had with your son, frankly it's not realistic. He's an adult now and has another family so you'll have to renegotiate.
Consider your son and his situation and what would make him happier. Do the same for your dil. Then do it for you. Work out strategies. Simple things first. You want to talk to your son on the telephone? Speak to him after a meal, when he's on his own and not when he is busy with dil. Make the call short, and be the one to end it. Make sure he enjoys the call. Happy voice, happy topic, focus on him. If you pick a bad moment (ask) apologise and ask when you could call. No hurt feelings, nothing unhappy or controversial.
Never, Ever Write. No letter, no emails. Without a leaven of facial expression and/or voice expression the written message comes across far too strongly and can be held against you for ever.
You can turn this around and get a good relationship happening. You can never get back what you had, don't try.
