What should happen and what is likely to happen [see details]?

Beth loves Albert and is all into him. They date and flirt but he only likes her more as friends and bunk buddies. She wants to have a long-term relationship. No matter what Beth try she cannot win his heart. He has eyes for Kimiko, which burns Beth up. Though Beth doesn’t care to be a mother she know Albert wants to be a dad, just not yet. She believes if she can produce a child for Albert his heart would soften for her. She also knows Albert always ”glove up” before they have sex. She goes over to his house with hard liquor because she knows Albert gets drunk easy and she takes some meth because Albert is recovering but boinks like a stallion when he has it in his system. After Albert is well on his way to being smashed she slips him the meth, and when he is three sheets to the wind, yanks off his pants and underwear, uses her oral skills to get him ready and mounts him, no protection. After he deposits a load she deftly gets his underwear back on and leaves. He knows she was over but vaguely recalls the sex. When he ask her about it and if a condom was used she told him that she tried but he didn’t rise. She drops the bomb on him five weeks later to say she is pregnant and that he is the father, thinking he would be overjoyed; he isn’t. He breaks with Beth and she is devastated. She is going to get rid of the baby and Albert is fine with that. Beth then hears Albert is growing closer to Kimiko and decides she will have the baby thinking it would get in the way of him getting with Kimiko, either because she will know he had a kid by another or being saddle with child support.

What should happen for Albert to move on with his life without Beth, and what is most likely to happen? Can Albert salvage anything positive from the situation?
