Basically I have two questions. The first one is ...

1. I don't know. Telling you to keep your eyes on the goal would not be helpful. I see this question as similar to one that asks how to get to California. (You probably would be at fault* for asking such a thing.) I could tell you to head west, but that would be of no help to you on your journey.
2. Step away from this individual who is embracing non-nuclear family proliferation. If your biologic clock is ticking, then get some ear plugs or turn the stereo up.

You are doing part of a required job to farther your career, and you just don't like paper work. Maybe you should think about doing something else that you truly like or take the job for what it is and learn to like the misery.

About this guy, you have had four dates with and already talking about being married to him? You already found out that you needed to about him and children, and all the other things you have noticed about him that you don't particulary care for already, think what you could have discovered if you had married him. Call yourself lucky and forget him.

Hi Katarina

To most people studying can get very monotonous, its the nature of the beat so to speak but worth it when you qualify

I think your problem is that you need to break your studies down into studying and socialising, You should set aside certain times which are yours to go out and enjoy yourself, Make a few friends, go out for a few drinks, dancing in fact anything to make you laugh, then you will find your studing becomes less tedious

As to your second question, I think you should steer well clear of him and change you number to stop him texting or telephoning you, I suspect that he is a married man just out for what he can get. send him a final text telling him that if he doesnt stop harassing you, because that is what it has become, you will report him to the police. Harassment is a crime even by texting or telephone

Keep copies of his text messages and your requests to him to leave you alone, That should act as evidence should you involve the police

In fact it may be better to consult the police now, they may decide to visit the man and give him a "friendly" warning to stop

Good Luck

Take care!

You know in your heart that this is not the man you want or need in your life.  No need to ask anyone else for advice in this regard.  Please do not sell yourself short and think because you are getting older and are a bit lonely that you have to hook up with someone you are feeling lukewarm about.  It will do neither of you any good.
