simpleHeart,
Reading through the posts and the way he is behaving towards you. I can only conclude that he is not being honest with you about something.
He can easily find find time to communicate with someone he loves.
How did he ever manage to win your heart?

In any relationship there are things that need to be taken care of and nurtured.

If you put a lot into the relationship, but your partner seems to put nothing or very little into it, that’s a sign that your partner isn’t committed to either you or the relationship.

If you're not being respected, then the relationship has to change. Mutual respect is the foundation of any relationship. Without that, the relationship is doomed, because something as basic as that is unlikely to change.

If you’re being lied to or cheated on, then you aren’t being respected. You can try to repair the relationship by talking things over with a liar or cheat, but don’t fool youself. That relationship is over.

If being in the relationship is putting stress on you or it seems like it’s unhealthy, then please try to visualise the future. Ask yourself where the relationship is going. Does your partner wear you out?

If your partner gets emotional over the simplest things or constantly critises your every move, that’s not healthy. That is called a high maintenance relationship. Some people can thrive in these situations. For most of us, we’ve got to get out of the relationship and find a healthier one.

If everything you do is a mistake or a negative on the relationship, this is no good for you. Your partner needs to let you feel appreciated. The overcritical partner not only brings the romance down, but they begin to undermine your self-esteem.

If they think you are insecure, then in their mind they believe you are more likely to stay in the relationship come what may.
Don’t fall into this trap. If your partner doesn’t appreciate you, you can find someone who will.

If you really do strive so hard to stay in a formerly romantic relationship that includes the above "IF'S" then you're likely in denial.
Most of us have been there in some shape or form. BEFORE
