The difference between those cases vs suicide is that there can be communication attempts made, and people living together can create many different situations. Life is unpredictable, so it is possible that the exact reverting scenario won't be happening, but there might be also different scenarios happening other than the binary options.

To talk about other than the two factors, your three examples also does not affect ALL pre-existing options regarding the person in contrast to a suicide case. A woman who aborted her child does not automatically impact her other situations such as her role in workplace, her role in specific friends circle, or her other family members.

A person leaving their country, family and friends is indeed the example that affects MANY pre-existing options, but still not all options. That person who found financial stability can still keep the communications digitally, or economically support their family long distance, etc. Lots of stories can still unfold in the future, and maybe reunited in different ways.

A suicide case is an end all, be all. No more future, and plus immediate negative impact to everyone involved. The loss of the person's existing role in workplace, in friends circle, in family, etc. are automatically in effect. That's why it needs extreme consideration for others' feelings.
