Blamed for all the bad things that happened!!!

Stressed, depressed, sad & hurt on how i am blamed by my partner for all the downfalls he experienced in his life. Even the death of his mom, his separation from his children from previous partners (which is his decision to returnthe kids to their mother). Even when his eldest child whom is left with him run out of budget & i cannot provide money (i am pregnant now and no work) he blames it on me and tells me... wala akong silbi. When i was working, i helped and provided financially for him and his 3 children and mom. Now he do not care about me and our baby as fo him i am the malas in his life! How and what can i deal with this!
