Translation of selbstverliebt

Study material is not easy to find. Unfortunately I have not received any such material yet. To give your students brochures and leaflets is in my opinion not the ideal. It cannot be compared with online studies.
Therefore we use only the Vocabulix dictionary in our class. It has good features and a large vocabulary base. I will have to send you a few sentences for rewriting if that is OK with you, because the whole is mixed up.
That's a great deal. I know that in the beginning it is difficult to have conversations, especially if you're not stable with vocabulary. Actually, your English does not seem so bad. Have you ever taken a course?
