I don’t even know what to call it ?

So ladies so let me tell y’all a story .. me and my BD , have been broken up since .... May-ish my birthday fell in June he took me out for my birthday , cool ? Yeah ok cool . So we now live in different houses where as I let him come over and spend the night with us and we still do “relationship” things like I still cook him dinner and make him lunch . Blah blah you know . So sometimes he didn’t call or talk to me , I was conflicted because one moment we’re a family next we don’t exist so like anyone would do I asked “what are we doing because if we aren’t working on a relationship , everything else needs to stop” he said ok an he was sorry then came an spent the night , needless to say I ASSUMED that was him initiating us working it out . Boy was I wrong . He would even hold me not kiss me or say he loved me no matter how many times I mentioned it to him . So I said “this cannot be us I cannot be your girl and u show me no love and affection “ so then he started acting as if he was trying to show affection . So fast forward. Still got no where but stuck stupid in love lol a guy brings me flowers to my job (never knew he was even looking at me , never knew or spoke to him) so I bring them home my dear bd sees them on one of his night that he wants to come over and is instantly jealous. But has yet to set clear as to WHAT R WE DOING . I continue to ask him what r we he never answered so this past weekend I went and hung out with my mom and some girl friends . There’s a guy he comes and sits with us we r all laughing and talking . Ok no harm done RIGHT OR WRONG ? I felt did nothing wrong . Next day bd txt me saying “so what we doin u just wanna put me on child support or what” soooo idk if someone he knew saw the guy and I or if he was just salty about me hanging out because he feels guilty about him hanging out when we was together but he won’t speak to me and I’m not goin to lie my feelings r hurt because I still love him he said he was coming to get our child NEVER SHOWED UP AND NEVER REPLIED WHEN I TXT AN ASKED . But mind y’all when we was together he use to flirt thru social media with all kinda women and then hang out with his friends A WHOLE LOT I rarely ever hung out .. so I’m confused as to why tf he so mad and why tf I keep being sad when I know I did my best in trying to be with him . This is my first REAL love and my first child so I love him on a deeper level than just my bd . But none the less lady gentlemen anybody help me cause I’m HURT hurt .
