I find this only half holds up.
You're right in that you do not choose to be born to your parents, but you do choose to enter a relationship.

But in both cases you do not choose how you feel about them.
For example I did not choose to feel disconnected from my parents (mainly my mother) the way I am, that was just a result of having been raised in a mainly argumentative household.

[hider=Clarification cause that on its own makes it sound abusive]
I was born with Autism at 3 years old, and was almost immediately being into ABA (Applied Behavioural Analysis) Therapy for the next 12 years of my life. We talked on this recently and she admitted to having reacted to me largely in fear in that if she went easy/allowed certain behaviour's to slip by that it would permanently wire itself as I got older and mess me up. So she was unnaturally paranoid, easy to freak out as a result. Especially when she is typically a very emotional person and I tend to be a very logical and hard facts sort of person.

We're currently working on fixing/improving the relationship. But it wasn't abusive, just we spent so much time arguing growing up I never had a chance to grow close to her.[/hider]

And at the same time I did not choose to feel close my girlfriend at the time either, it was the natural result of chemistry.
Neither was me consciously going "I'm going to like/have strong feelings for ________ but not for ________".

You can easily end up feeling very close to your parents and not to your partner, very close to both, not close to either or very close to your partner but not your parent (as was my case).
If it ever is a case you feel very close to them, the individual committing suicide will cause mass harm for you regardless of how you know them.
It's just that in your case it's your parents you hold the closest relationship to, while for others it may be a partner, or a friend, a sibling, maybe even a pet. Everyone varies.

Bottom line, regardless of relation suicide hurts if you're close to the person. But it does not change the fact that it's that individuals chose to do what they wish with their life, not your choice.
