Changes in the sense of identity from continuing or terminating romantic relationships were investigated in university students through a longitudinal study conducted at three time points. Participants were university students with a boy/girlfriend at the first survey (N = 192, 61 men and 131 women). At the second survey, the romantic relationship of 20 participants had terminated and they did not have a new partner (Time 2 ending group). At the third survey, the romantic relationship of 14 more participants had terminated and they did not have a new partner (Time 3 ending group). Two-factor-mixed-design analysis of variance was conducted on four scores of the Multidimensional Ego Identity Scale, with the time of survey (3) and the state of dating (3) as factors. The results indicated that interaction was not significant for any of the four scores. It is concluded that even when young people lose a lover, they are able to maintain a sense of identity owing to feedback given during dating time by their ex-partner.
