Cheating.

my bf cheated on me when I was pregnant...he signed up for these dating websites & tried to meet up with girls and have sex... a couple weeks later he texted this girl off of twitter... I asked why he said he felt lonely... I forgave him because I don’t want my daughter to grow up with a broken family like mine... my daughters 2 weeks now and I feel like he’s cheating again... he’s been distant and cold to me... and idk what to do... ):
