Need advice rebuilding trust with husband and doing things to make him feel loved (LDR)

I'm currently in a LDR with my husband, and I'm broke, to make matters worse. We're doing a trial separation; I'm living with my parents with no car, an hour and a half away. I'm 25 (f) and he's 29 (m). We've been together for almost 3 years, married for 1 year.

I have done royally evil things to him, like threaten suicide to "make him happy" (as if he would be happier if I were gone but with that kind of guilt) and not communicate effectively about my needs, as well as refusing to meet his needs of communication, willingness to be open and honesty, and feeling loved. This has not been out of malice or hate, but out of selfishness and internal guilt that "I'm not good enough for him so why should he want to be with me?", even though he does want to be with me.

We've fought constantly about him not getting his needs met and he's been very clear about his needs, so that's not the problem. He refuses to lay his heart out anymore, with the risk of it being trampled on more.

He does want to be with me but I need to do some serious work. What can I do in a LDR to show my beloved that I still do care and want to be with him, after all of the things I've done to violate his trust?

TL;DR: I have violated trust in my husband and he no longer feels loved, how can I go about fixing that from a LDR stance? Relationship therapy is already on the table...logistics baby, logistics.
