<human>: Can you provide a brief rundown of the text in within 3 sentences?

We met online, exchanged messages for a few weeks, then met in person and hit it off pretty immediately. Preceding this relationship I had been single for about a year. This period of being single is really the first time I had felt comfortable and confident being independent since I started dating as a teenager. I also explored the world of casual hook-ups, which I actually found to be fun.

I had previously been in other LTRs that were not very healthy. She had been coming out of an emotionally abusive 5-year relationship.

I initially wanted to keep things casual, but we had hit it off so well that we just went with it. I had trepidation about entering anything long-term, but I liked her a lot and felt like I couldn't just throw away the connection we felt because it seemed to be something rare.
3 months into the relationship, due both our financial situations, we decided to share a room (she's on the lease, I'm not) We have a healthy, functional relationship, and I care so much about her, but I miss aspects of being single and independent.
 
So throughout our escalating relationship, I have felt conflicted between feeling as though our relationship is wonderful and healthy and feeling as though I am unprepared or unwilling to make a big commitment. I've thought about and brought up potentially opening up the relationship, but she was not super comfortable with the idea. 

Because our financial situations prevent me from moving out for the time being, it's really difficult to think of ways to deescalate the relationship. I really care about her, but I have this nagging feeling of restlessness. I'm also incredibly worried of hurting her in the long run- that is the last thing I want to do. 

Because of her history, I'm worried that she'll never end it on her own volition, she took back that asshole repeatedly and even told me she probably would have wound up back with him had she never met me. This adds even more pressure on me because I feel as though I'm the only one who will notice anything wrong if anything is amiss with the relationship.
<bot>: Living with my SO, feeling happy and healthy but also restless and unsatisfied. Unsure which feelings to listen to. I miss being single, but I feel like I'd be an idiot to let her go any time soon.
