Out look on social media

Long story short my boyfriend and I have been together for a while we were together for 7 years had a child split for almost 3 years within that time I got pregnant with our second child we didn’t have a label I tried having him involved but things went south at the hospital when delivery time came fast forward we now have three kids together and he has another child I accepted her as my own just like I do any child no matter the parents well things have been very bumpy I the point when we fight he changes his relationship status and deletes me off all social media we have now been going on about 4 months and he still has not added me back or changed his relationship status he also has been deleting his snap chap it’s okay to be friends with all these other chicks but not me he’s even gotten to the point of accusing me of having a fake Facebook page but he has the same chick on Facebook and snap chat seem like cheating to me or the lines of it
