toxic relationship

i’m 31 weeks and my boyfriend has been really distant lately and hiding his phone a lot. RED FLAG. found out he’s been telling this girl that i’ve been cheating on him for almost a year (which is not true) and that he thinks that our baby probably isn’t his (but she is his). today he went for a run for 2 hours, that’s longer than usual. checked his phone and he was out w that girl then came home like nothing happened. i’ve been w this guy for 5 years and things like this have always been happening in our relationship. if you see the toxic signs don’t ignore them like me.
