Losing the spark 😥

So me and my boyfriend have been together for two months and well everything was perfect and we are so in love and our relationship is amazing but as of last week and on to now he doesn't touch me the way he used to ... There used to be a lot of teasing , foreplay I guess you could call it and now he just doesn't seem in the mood and I understand he's going through some things with his dads birthday coming up (his father past when he was 13) and I hate to force him so I leave him alone but its killing me and I don't know how to deal with this ... Please help me
