I have been in my relationship for nearly 16 years , we split 7 years ago but got back together after 6 months . We have a son together . Our relationship has always been up n down, I have my own place but since Covid we have lived together full time again. Basically since Xmas it has been awful , she took up new hobby where she’s out 2 evenings a week, they also go out socially and lot of texting too, I’m new year I basically accused her of being unfaithful , no evidence just few things. Since then we have just grown apart and zero connection now, we talk and talk but nothing changes, it just feels like we have run out of words to say to each other . I feel she has little time for me anymore, even when we go out which is rare it’s seems false , we both say we love each other very much and don’t want to split but we don’t know how to fix it? Am I being unreasonable thinking she denotes too much to her hobby and new friends ? Yes I’m insecure I know that but she can be very cold too. We had some magic times together and recently I thought of walking but didn’t . Any thoughts on how to fix things as I seem to have run out of ideas ?
