It's very normal to mourn a loss, whether it's a close relative to natural passing, or a relationship that went bad.
Dwelling on the loss is the problem, though it doesn't sound as if you're doing too much of that. It sounds more as if you're reflecting on how to avoid choosing a bad partner, in the future. Good for you!!! Putting aside education for any relationship is a really, really big error in judgment - at least, it was for me. Our education is more important that we can possibly imagine, and it's a good thing that you didn't end up marrying this guy. It's so very easy (and, cheap!) to get married. Getting OUT of a bad marriage costs thousands in fees and untold emotional damage.
That your family "resented" your relationship with this person should be re-examined. I think "resented" may be a misnomer - perhaps, they were concerned and, rightly so. Often, those around us can see far more clearly than we can, so forgive them for their concern.
Best wishes to you!
Being hurt in a relationship can be devastating, especially for those with a low self-esteem. If you want to be successful, in a significant relationship you need to have a healthy self-iimage. People with a healthy self-imaghe do not get hurt so much in rejection of love. They know they deserve better and start looking for a BETTER relationship very soon. But if you have a low self-esteem rejection in love can be really devastating. It seems to reinforce a previously held negative self-image. It can trigger a depression, and this means a pre-existing tendency to become depressed was latent to start off with. Having a low self-esteem also leaves you open to manipulation by others.
You might think that a low self-esteem is a "psychological" matter, something you have acquired because of bad childhood experiences or learned negative ideas about the self. Very often people with a low self-esteem can trace these feeling back into the past, which seems to confirm that it has been acquired because of a learning process or because of "bad" parenting by a child's parents. That of course implies that you can be talked out of these negative feelings by a long process of talk therapy.
You may be surprised to hear that there is a much easier method of overcoming a negative self-image, if you start to realize that a low self-esteem is simply caused by your body's inability to produce feel good neurotransmitters. This may have been going on for a long time. Therefore if it is not "psychological" what is it then?
People who suffer unknowingly from a silent illness - such as hypoglycemia - have problems producing feel good neurotransmitters such as serotonin and can become depressed. One sign of that depression is having a low self-esteem.
The reason is that hypoglycemia means the inability of the body to produce biological energy called ATP from carbohydrates in food. That energy is essential if the body wants to manufacture feel good neurotransmitters and right hormones from nutrients in food. Thus the body lacks the necessary energy to convert tryptophan in food to serotonin. And because serotonin is also the forerunner of melatonin - the sleeping chemical - many depressed people also have problem with have a restful sleep.
The beauty is that you do not need any drugs to overcome depression, low self-esteem or insomnia, but to simply adopt the Hypoglycemic Diet.
Give it some time on the hypoglycemia diet (about three months) and you will start to feel much better about yourself.
As I said it is important to have a healthy self-image (in the literal sense of the word) to be successful in love and life.
Now you are ready to to do some self-help psychotherapy by studying:
Summary of Self-help Psychotherapy
in its entirety from beginning to end. It includes a program showing you how to overcome a negative self-image, and assertiveness training program, communication course and values clarification course. You may need the help of a CBT therapist to complete the course. But most people will get better at it by themselves, by just reading the articles over and over again.
I can assure that you will never be hurt again in a love relationship. The course also gives you some insight into your prospective partner. You will never choose a bad apple anymore, and if you made a mistake, you will learn from the experience and become emotional richer, instead of poorer!
