wife wants her space, doesnt know who she is

[mastersolo]

so life has got really confusing...
we are still switching between the house a week at a time(i get the house and kids for a week then she does). W pretty much this whole time has been really hateful, bitter, easily irritated, and so forth. she even contacted an attorney about divorce and we were supposed to go talk to her to see if she could just mediate rather then us get attorneys so we could save money. that was supposed to be last friday (a week ago). when i called my W to see what time and where she said she will just reschedule because she didnt feel like going. sooooo that night (friday) i get a phone call then 2 texts at about 12:35 at night from her saying how she misses my touch and will always love me but doesnt think i can change and be what she wants. This caught me way way off guard because she hasnt said anything emotional to at all this whole time. then on saturday i asked if she would like to go to dinner, she said she had already made plans with her grandparents and brother but maybe tomorrow. so i said thats fine. so the next day (sunday) we took our kids to omsi then she asked if we were going to dinner. i said yes if you would like to. anyways we went to dinner and had a GREAT time, great talk, everything. we started talking about us, the past, the present, the future. she shared how much she really misses me and loves me, and i told her my feelings which were the same. she even started to tear up and cry. she said that is the first time she had cried through this whole time. we ended up going to to get our kids together and stayed at the house together for the first time in a long time. we made love and cuddled all night. i honestly felt loved for the first time in a long time. the next morning/day was like we were back together. i got to come home and do dinner, help with the kids and what not. she was sick a few days so i was able to take care of her. then on that Wednesday she said she wanted to talk about things. this is where im confused, when i got home she said she still wants to be separated because she doesnt want to get back together for the wrong reasons (just because she misses her family/ misses being comfortable / lonely). so she wanted me to go back to my moms and get back on the schedule we were on. tho she has been way way nicer to me as far as our talks go and she asked if i wanted to go to the auto show this weekend.
so with all that being said im so confused...... she acts like she wants to get back together, then tells me she still wants her space... at least she isnt being so mean. i guess im just being patient and waiting things out. this just kinda [censored] because its playing with my heart, not just for the relationship with her but because my S5 and S1 were so happy to see us together those nights doing all the family stuff. anyways any advice would be great!!!
Thanks!!!!!
