Since there isn't much else going on today...
For the one about not having sex in weeks, create some passion. Have a nice dinner together, have him give you a massage in bed, something. If you initiate, maybe it will make him initiate more. But I think it's natural for the initial passion to fade.
For the one about life being too hard, it would only be harder on everyone you love if you ended you life. Nothing is that hard or terrible to be worth taking your own life, or wishing it be taken.
And the one about changing your name is just weird to me. Why will you only change it if he asks? You want to change it, so change it.
