Could anyone help me shed on light on a very confusing ex?

ok phew lol tht was long. but i feel tht he is trying to make u jealous with the whole pregnant situation. If his girl told u she couldnt get pregnant come on the guy is obviously lying u hardly no the gurl and she isnt gonna lie. Deep down inside him he still has feelings 4 u and wen he wants to text u is becuz hes thinking about and he wans to get back in ur life slowly with a text. n whts up with him not telling u about his girl. seems like he was either embaressed of her or just thought id b nice to have 2 girlfriends. Over all, hes an idiot u should b with a guy like tht. i c u can do better. go out somewhere and enjoy ur life and live it happi!
