Relationship advice

So I’m talking to my ex and we broke up due time and we just started talking again things were going good conversations flowed the main reason why we got together in the first place she was my first everything to when we started talking again she started showing me her boobs the next day and tells me I know you missed these and stuff she wanted to do with me then tonight she turns around and says “I want bbc” and I joking say I got you twin and she says “not you your only 5 inch” which she wrong but not the point I’m also 324 she’s knows I’m big one of the things she likes about me too so I take her joke to the chin and we continue talking but then she gets on the phone with other guys and dating apps while talking to me and I’m just like damn and our relationship is confusing to boot like idk if she actually wants me or if she just likes me as emotionally support I texted her how I felt about what she said/did and all she said was “ok sorry” no I’m a master of cutting people off so if that’s what I need to do I’ll do it let me know please
