Hey guys,
i’ve been extra clingy to my boyfriend lately. i’ll call him/texted him so much through out the day. i’ve come to the conclusion that i do that because of my anxious attachment style and lots of insecurities. so i’ll call him not to be pleasant, but to complain on why we don’t go out on dates, complain about why he doesn’t post me on social media, complain about why he doesn’t call me or text me enough anymore. recently he has been telling me that he doesn’t care anymore. for example i told him that he’s been drinking too much and he says he doesn’t care. yesterday i asked him if he wanted to go out to dinner and he said yes. i called him about 30 times between the hours of 7:30pm-10pm wanting to know what happened and i texted him as well. he called me back only one time at 11:35pm and never answered any of my text msgs. i woke up at 3am and i called him and the only thing he told me was that he left his phone is someone’s car. someone? it could have been a guy or a girls car I don't know. but yeah i also have asked him a couple of times through out the week if he’s losing interest he says no. i ask him if he wants to break up he says no. i’ll be honest, im not confident by any means and it’s not his problem but he’s not helping with the way he is treating me. i’ve decided to let him come to me, i’m not going to call, im not going to text. i know he is overwhelmed with the way im coming at him by calling and texting him, but it makes me sad that i can tell he is losing interest and does not tell me anything.
