Give your family some time to accept the pregnancy. It's probably come as a huge shock to them. They probably didn't know you were TTCing and just weren't expecting your big announcement. Due to your history they may not have expected you to go through another pregnancy and are very likely to be extremely worried about you right now and are struggling to find words that wont upset you. Nothing excuses their comments about your ex though.

Please don't take this the wrong way but depressed people often push people away and don't realise they are doing it - they feel they are being pushed away. If this is happening to you, you will not be able to see it, but those around you will. I watched this happen with my ex husband who suffered from depression, it was really hard to witness it and I felt completely unable to help him and it got increasingly difficult to communicate with him. Perhaps this is what is happening with your family right now.

My dad was not exactly over the moon when I announced my pregnancy. He just wasn't expecting the announcement and was very worried about my future (things were rocky with my DF and I) and my finances. He was worried about his little girl (I was 41 at the time, but I'm still his little girl). We just kept spending time with my family and little by little he warmed to the idea and by the third tri he was excited about it and now he's delighted to have a grandson. He also thinks the world of my partner yet I can assure you he didn't at the time of the pregnancy announcement. Sometimes things just take time.
