4 months pregnant left my babies father due to a huge arugment. I was gone for two days came back home to only find a unused condom in our room. He says its probavly his brother since he lives with us of course. I continue to ask him many questions around the fact i found the condom. Of course he blames his brother and denies everything. I feel i know that it was his but i dont want to belive it honestly. Every since i been back he actually been a better person. He support my every need. He very lovey dovey lol. Im thinking because he know he has a secret and he dont want to lose his family so of course he wants to please me in everyway. Should i leave or just leave it bee
