Im sorry ahead of time if this is long winded...but im feeling crushed and dont know what to do...

A few weeks ago i found some searches on the computer history saying
"Why am i attracted to my daughter" and another simular....Our oldest daughter is 20 by the way...I confronted my husband (her real father) and he said yeah he looked it up and blah blah blah...I said to him, no matter what you say, because he could make an AWSOME salesman... for real....no matter what its wrong, wrong wrong wrong and how does something like that even come to mind when looking at your OWN daughter?!?! Wish i was able to "talk" this post because its just not sounding right to me...anyway...........

I just cant let it go...we dont talk about it besides a comment here or there because of our 9 year old daughter being around all of the time...shes homeschooled and such....

Now when our oldest calls he picks up his phone, she calls him more because he breaks easier when she wants something....anyway i noticed hed get up and head to the bedroom to talk and whisper....I brought that to his attention and he acted like it wasnt anything unusual...well it IS hes never done that before... Last night she called and when picking his phone up he said..."Oh its _ _ _ _ _" (his sons name) and then he talked quietly BUT stayed in the living room....I was busy getting our youngest ready for med and getting my meds together so i was in and out and couldnt hear the whole convo but it was DEFF our daughter as she wanted to talk to me toward the end of the convo... I asked my husband why he said "Oh its _ _ _ _ _" if he KNEW it wasnt? He says he said sometihng like it might be him calling or this or that...Hes lying to me now?

I know our oldest daughter doesnt even KNOW this is going on...and shes NEVER EVER done or said anything out of order to him and doesnt dress out of line... I dont get it...

Ive lately been looking for places for rent for my youngest and I to go...Whos to say when our youngest starts to develope that he wont look or "think" sexually towards her!!!!! I just dont trust him...

Also hes starting to get angrier and meaner to us...saying things that hes never for all the years ive known and been with him...

Im on SSI (disability) and only make a wee bit over 700 a month...where i live i CANT at all rent anything and the apartments that are based on income around here are in horrid neighborhoods...I dunno what to do or how to get out.....Theres also NO one i can talk to about this...im not close to my family and have no friends IRL.... Thanks so much for reading and any advice in advance...
