Wife Likely Cheating--Need Help

[sadpanda]

My wife moved out recently. I am pretty sure that she is duping me into paying some large expenses she has over the next several months while we attempt to reconcile. I think she is stalling me with fake efforts and meanwhile is in another relationship. This is really eating me up. I need some help to find out if this is really happening.

So, she and I share a phone plan, but use different cell phone with different numbers. I am the only payer on the plan and have been the whole time. She is text messing an enormous amount and goes to great pains to hide who they are coming from and what they say. I think the answer lies in her text messages over the past six months. How can I see them if I don't have access to the phone? I tried going to the wireless website and all it tells me is how many texts she has received, the number they are from, etc. but not the actual text. Is there a way to see the actual text?

OOT please help!
