PLEASE HELP!! On the verge of giving up on life

So about 4 months ago I broke up with my ex . Of six years We were constantly fighting because all he wanted was to go out . A month into it he calls me and tells me he misses me m cry’s to me that he’s with this new girl but he so bad wants to break up with her and be with me . He goes on saying everything is different with her and he doesn’t like it . The sex, the way they tlk to each other. But I didn’t want to get back with him at least not rite now . I was crushed when I found about her but I didn’t think it would last and hopefully we would be together later in life . Well its nkw momth 4 and I just found out this new girl is pregnant ... I have no idea what to think it makes me sick to my stomach . I question whether this is god telling me I couldn’t have kids so she gave him what he wanted ! Or is god telling me we wer not supp to be together . I havnt slept in days because I am heart broken . Plz help I’m lost and questioning why god has put me through this . I’ve always been the good one I never cheated like him ... I just don’t get how god thinks I can handle one thing after another ..... plz help
