When is Enough, Enough

UPDATE: Scenario and Pre-question
We have been dating for four months or so, and there is potential. There were a few times early on where we did not see eye to eye on our 'situation,' and there are still times when we cannot read one another. That's all great and good, right? There are a few things that just aren't quite as easy as they were when dating in college. I don't have a car anymore. I sold it before I moved because I travel all the time for work and can get to anywhere I need to in Chicago via taxi, CTA, or Metra (until the state fails to fix the transit crisis, that is). She lives in the suburbs, and I live in the city. So, it takes her like 20 minutes to get to my place. It takes me about 40 via train, but that no biggie because it's only like 5 bucks for the whole trip. All that aside....is there any reason why I am still footing the bill for every excursion we go on? And when she offers to pay or pay me back for things we've done, it's always like somebody just jammed a match in her butt (the look on her face, that is). If you don't wanna come off any cash, don't. But don't make me feel bad for you wanting to give me money. What type of bull is that?

I've officially decided to make this update a rant. How about this? I let her borrow a suitcase. It got damaged, by the airport or her. She played like she didn't know, but the handle that got broken off was in the pocket of the bag. So, barring her doing it and not wanting to fess up, wouldn't you think she would try to get the money for a new bag from the airport? NOPE! So, now my bag is missing a handle, and I don't have a new one on the way or anything. I implore you, WTF?

Two of my face towels are bleached now because she used some product on them instead of asking for or looking for a cotton ball. Will those be replace, most likely not. Not even close to being a big deal, but it's under my skin when combined with the other stuff.

...I gotta stop before I put a damper on my whole day.

So...*sigh*...I don't know what to do. I like this woman and could possibly end up loving this woman, but...I just can't see the forest for the trees. She's great, overall! There's no denying that. However, I need my space. I have a 1 bedroom apartment for a reason. I don't like having roommates. This is no secret to her. It's also no secret to me that she's clingy, also something I don't deal with very well. While I like knowing how much she's into me, I can't help feeling like she just wants too much. She wants to spend too much time together. We work in the same building for the same firm. So, when I'm at the office...who is she making lunch plans with? Granted, the people in her group aren't my first choice of individuals to socialize with, but when you mix the office lunch with the office coffee break with spending time with her on the weekend with her spending the night with her staying another day and wanting to talk on the phone all the time...I might as well be engaged.

Is it really that deep, ladies? Is it me? I'm pretty much in a stage of utter discomfort, but I know it'll break her heart if I tell her. I would much rather let the truth be known that to be aggravated further and further by little things that don't matter because I don't address the big picture. Suggestions?
