Yup wrong again...

So my partner left and I felt abandoned even tho I was told the circumstances it still doesn't stop how I feel... So when she popped back up it sent mixed emotions racing through me... Yes I was happy but at the same time I've been hella cautious at the same time I've been feeling hopeful... Now while she was gone I promised myself I wouldn't let any1 break me down again so I keep people at a distance...but I found other vices... Even accidentally mentioned how important something was that I lost earlier but it didn't matter... she didn't notice... After a fairly decent day the shyt hit the fan... One of my friends/exs called me from jail... I haven't had much contact with this person as their gf hates me! I didn't try to hide it hell I was just as surprised as she was when the phone rang... No they haven't done anything to me personally but my partner claims there was a secret she knows... In any case I didn't answer the 1st 3 calls but she pitched a fit and said she was going to the living room... I asked where she was going and why but it didn't make a difference... So the phone rang again and she came back in... I answered it asking if I needed to make other phone calls or something... She starts snatching cords and unhooking chargers and I giggled cuz I wasn't hiding anything... but that just made her more upset!  Now I know I haven't done anything outside of some stuff on my phone Im not comfortable with any1 seeing but everything ended up getting more and more physical... I kept trying to scream that I couldn't breathe and she said she didn't care... My son came as I told him to call 911 but he couldn't unlock the phone... Needless to say she eased up on me to reach for him and get that phone and when she did I tried to get my phones back and bit her to get away... I ended up with a busted lip and a few scratches but whats worse is that I haven't done anything that she's accused me of! But I'm torn as we have kids together... She suggested counseling at one point but I'm not even sure that's still an option... I do love her but she doesn't see it... I guess like I struggle to see her love for me... She's still accusing me of the stuff she's done to me... I tried to show her there was nothing to it... but as usual she didn't want to hear it...
Im so lost as I feel like ive lost my family all over again... no clue what to do... :'(
