What are the property abandonment laws in Texas?

[zacchaeus21]

In August '08, I moved in with my roommate. In late May of '09, my roommate moved out of our place and in with her boyfriend's family. She packed and moved all of her "most important things" (ie books) and asked if I would mind holding on to some of her stuff and, since I was still using some of it (kitchenware, etc.) I said I wouldn't mind, as long as I were still in the apartment. At the time this happened, we were on a month-to-month lease. I told my landlord I had a friend who wanted to move in. She said it was OK, and to have them come in to sign the lease. The middle of that week, I moved in the new friend. On Friday, we went in to sign the lease and the landlord said she wanted to raise our rent and that she wanted us to pay a new deposit. The apartment wasn't worth the $600 we were already paying (literally) and we thought it was inappropriate for us to have to pay another deposit. My friend decided she didn't want to move in after all and the next day, she moved everthing back out. Knowing I could neither afford the place on my own, nor find another roommate, I packed up all of my stuff (and what my former roommate) had left. Not having my own car, I did my best to get everything out with the help of friends but a lot of my stuff (and the former roommates things) were left behind. Despite telling the former roommate that I was being "constructively evicted" (for lack of a better word), she never offered to help get her things out. The things of hers and mine that I was able to get out has been in storage since this time. She has made a few attempts at getting some of her things, and does indeed have part of what I was able to get out. However, the last time she made an arrangement to get her things, we agreed to meet at the storage place one afternoon after work. I made sure to keep myself on my parents side of town (which is where the storage facility was). I never heard from her. Her attempts at getting in touch with me have been few and far between. Today, I got a call from her boyfriends mother saying that the roommate had moved out of town and was wondering if I could meet up with them to give her her things. I don't have half of what she thinks I do, and I don't think I should have to go out of my way to get her things, considering
a) the roommate has bailed on several attempts to meet up and
b) the roommate is not the one contacting me, despite my number having not changed, and she also knows where I work.
I'm a newlywed, working full time (and looking for a part time position) and preparing to start school in the fall. My husband and I are very family oriented and are often visiting all parts of the city in family functions. I am too busy to worry about trying to get some miscellaneous items to a person who only shows concern for her belogings when it is convenient for her.
What are the laws governing this?
Could I be held reliable for not getting all of her things out of the apartment in the first place?
All of the things that I do have has been in storage for two years, and we have not gotten even an offer to help pay for the storage.
I feel bad that I was unable to get all of her things out (I'm just that kind of person), but in the the same regards, I lost a lot of my things, too.

We have put nothing in writing as far as who will store what, when and for how long.

You have done all you need to do, tell the former roommate that there is x number of dollars owed on the storage and once that is paid you will meet them so they can recover their items.}{
