Both of my boyfriends have said that I don't show my love very well
I've picked the same quote as Lovely Friend.
Your past and present boyfriends are no measure of your ability to love or to express love. You've been brainwashed into accepting worthless opinions as fact.
Grape I know someone your age who was very reluctant to end a five year relationship that everyone else could see wasn't going anywhere and was actually a huge obstacle to their happiness.
I think the concerns for them were the perceived 'investment' in all those years, hanging on to a belief that they could change the other person or that they would miraculously change by themself and also fear of the future, fear of cutting loose and being alone.
You can be lonely in a relationship as well you know, if it's not the right kind of relationship and you sound lonely to me, unsupported and downtrodden.
Posters absolutely do realize that it's not as easy as someone saying LTB, life and emotions are more complicated than that and it can take time to either organize, or to even accept the realization that you should part.
In your case though and apparently over past threads too, opinions of this damaged and damaging relationship are almost unanimous.
I recommend you copy and save this thread and keep reading it over and over.
