Disappointed in my family.. need advice

Long story alert, but for background purposes: basically when I was 21 I decided to start studying law. I paid for this myself as my parents couldn’t afford to help and I have never held this against them. I worked full time and studied at night.

I’m now 30, married and have a baby on the way. I finished my degree last year June and have just completed my board exams (the last step before I can be admitted as an attorney).

My problem starts here... my mom wasn’t the most involved growing up, she moved cities when I was 8 and started a new life elsewhere and we saw her maybe once a year. When I was 19 she wanted to get more involved in my life, while it was difficult dealing with this at the time, it’s now at a place where we are close (not motherly, but almost like close friends). I have two sisters who I have always thought I was close with but recently I have been questioning this.

Every time they have some urgent issue in their life, I am there for them. I listen and make time and acknowledge their issues and try to offer reasonable advice.

Only when I was in my final year of my studies did my mom and sisters really start taking an interest in what I was studying. Up until then it was barely acknowledged.

When I graduated, I reminded them of my grad day and only then did they send their well wishes.

I wrote my board exams recently and failed one by 2% so the law society gives you ‘one last chance’ to pass by means of an oral exam. I told them about this about two weeks before the oral exam.

The day of the exam came and went (by some miracle I passed) and not one of them sent me a message before hand or after to find out how it went.

Every single member of my husbands family sent me a message.

They still don’t know that I’m now done. And I can’t find it in myself to even tell them. I burst into tears yesterday because over the last year, it feels like they acknowledge my achievements when they need advice only. And I have kept this in so long that I just don’t want to let them in on any personal aspect of my life anymore.

I just don’t know why to do, I’m not sure if confronting them is worth it, or if I should just keep my distance from now on. I’m tired of being there for them to receive nothing in return.

* this isn’t a once of isolated instance, my family have always been a bit like this and I feel like this is the straw braking the camels back.
